History

Formation and Early Activities (2014–2019)

YesCymru was founded in September 2014 by activists Iestyn ap Rhobert, Siôn Jobbins, and Hedd Gwynfor, initially as a small group inspired by the ongoing campaign. The organization's early efforts focused on supporting Scottish independence activities, including its inaugural public rally on 13 September 2014 in under the banner "All Under One Banner Cymru," which drew modest attendance and aimed to build solidarity across . Following the Scottish referendum's "No" vote on 18 September 2014, YesCymru pivoted to advocating for , emphasizing a cross-party, approach to normalize the concept within . Membership opened to the public in January 2016, followed by an official launch event on 20 February 2016 at The Old Library in , which attracted around 250 participants and marked the group's formal structure with an initial . From 2016 to 2019, activities centered on establishing local branches across , organizing public stalls at festivals and markets to distribute literature, and hosting debates with politicians to press for an . The group launched Radio YesCymru in August 2018 as a platform for pro-independence discourse, featuring founders like Siôn Jobbins as early presenters. By May 2019, YesCymru coordinated its first dedicated march in on 11 May, modeled on Scottish "All Under One Banner" events, signaling growing organizational capacity though still with limited turnout compared to later years. ![Welsh independence march in Cardiff, May 11, 2019][center] Throughout this period, YesCymru maintained a modest membership base under 2,000 and relied on volunteer-driven, low-budget operations, focusing on and awareness rather than , as independence support polled around 14-22% in during 2014-2019 surveys.

Expansion Amid Pandemic and Online Mobilization (2020–2021)

During the , YesCymru experienced rapid membership growth, attributed to heightened public awareness of divergences between UK-wide and policies, which underscored arguments for greater . In early 2020, membership stood at approximately 2,000 to 2,500; by spring, it had doubled to 5,000 within two months, fueled by online recruitment amid physical gathering restrictions. This surge continued into late 2020, with numbers exceeding 14,000 by November 5 and reaching 15,000 by November 11 after doubling in three weeks, as supporters cited dissatisfaction with Westminster's handling of the crisis relative to Cardiff's responses. Lockdowns necessitated a pivot to platforms, where YesCymru adapted its strategy to politicize pandemic-related issues through , emphasizing Welsh-specific vulnerabilities and policy contrasts to build momentum. Online efforts included targeted campaigns highlighting economic impacts on , such as border closures and funding disparities, which resonated amid broader fallout and debates. By January 2021, membership surpassed 17,000, reflecting sustained virtual mobilization that bypassed in-person events curtailed by restrictions. This period marked a shift from localized to national-scale online engagement, with YesCymru leveraging platforms for rapid information dissemination and member onboarding, though growth strained organizational capacity without immediate internal fractures. Preparations for the 2021 elections further amplified digital outreach, positioning independence as a viable response to crisis-exposed governance flaws.

Governance Crises and Internal Divisions (2021–2023)

In mid-2021, YesCymru experienced significant internal turmoil stemming from rapid organizational growth and disputes over the handling of complaints against members for their public statements on transgender issues. These complaints, often framed as instances of transphobia by critics within the group, involved expressions of gender-critical perspectives emphasizing biological sex distinctions, leading to accusations of online abuse and demands for disciplinary action. Leadership, including chair Siôn Jobbins, faced criticism for perceived inadequate responses to such complaints, exacerbating factional tensions between those prioritizing ideological conformity on social issues and others focused on core independence advocacy. Jobbins resigned on July 10, 2021, citing a in communication and the need for fresh amid these pressures, while later apologizing for failures in addressing internal allegations. Shortly thereafter, on July 31, 2021, regional member groups passed a vote of no confidence in the , reflecting widespread dissatisfaction with and decision-making processes. Interim chair Iestyn ap Rhobert urged members to respect differing political backgrounds and rebuild trust, but divisions persisted. The crisis peaked on August 13, 2021, when the entire resigned en masse, stating the move resulted from an "unsustainable situation" built up over multiple unresolved issues, including governance strains from the group's expansion during the period. This left YesCymru without formal leadership, prompting the appointment of an interim board and calls for professionalization to prevent further infighting. Analysts attributed the collapses partly to "" distractions, such as debates over transphobia policies, which diverted resources from independence campaigning and alienated members. Into 2022 and 2023, recovery efforts included appointing a new CEO, Elin Hywel, in September 2022, who emphasized refocusing on goals and keeping internal "sh*t" out of public view to rebuild momentum. However, lingering divisions over past handling of social issues contributed to membership fluctuations and operational challenges, with membership dipping below 10,000 by late 2022 from pandemic highs. By 2023, the organization stabilized under new governance but remained marked by the 2021 schisms, which former executives later described as self-inflicted wounds from inadequate structures to manage ideological .

Revival Through Street Activism and International Ties (2024–Present)

In 2024, YesCymru recommenced large-scale street activism after a period of internal challenges, organizing its first major March for Independence in on June 22, which drew thousands of participants carrying flags, banners, and posters in support of . The event, co-hosted with All Under One Banner Cymru (AUOBCymru), featured a gathering at Carmarthen Park from 11 a.m., with the march commencing at 1 p.m., and was described by organizers as a return to mobilization on the streets. Subsequent marches built on this momentum, including one in on April 26, 2025, where estimated over 6,000 attendees marched through the town, marking one of the largest turnouts for the campaign in recent years. These events signified a revival in public engagement, with organizers reporting sustained participation from families and supporters across , contrasting with earlier declines in visibility during governance disputes. The pattern continued with a tenth March for in on October 18, 2025, where thousands again filled the streets starting from the Events Arena at 11 a.m., proceeding at 1 p.m. to rally for separation from the , emphasizing themes of and cultural preservation. Such activities, held in diverse locations like historic towns and coastal areas, aimed to sustain momentum toward breaking polling thresholds for support, with YesCymru coordinating logistics including , speeches, and visual displays to amplify visibility. Complementing domestic street efforts, YesCymru expanded international ties by hosting a on stateless nations in , announced on May 26, 2025, to foster solidarity among movements. The gathering, organized on behalf of , convened representatives from seven stateless nations, including participants from regions pursuing outside established states, to discuss shared strategies for and global recognition. This initiative reflected a strategic shift toward cross-border alliances, positioning YesCymru within a broader network of non-state national movements while prioritizing empirical exchanges on policy and mobilization tactics over ideological alignment.

Organizational Structure

Leadership and Central Committee Dynamics

YesCymru's governance is led by a , later formalized as the National Governing Body (NGB), comprising elected and co-opted directors responsible for oversight, decision-making, and operational management. The structure emphasizes volunteer-driven leadership, with roles including chair, deputy chair, secretary, treasurer, and non-portfolio members, elected via annual general meetings (AGMs) or extraordinary general meetings (EGMs). In December 2018, following the resignation of the prior committee after members rejected proposed constitutional changes at the October AGM, a new Central Committee was elected. Siôn Jobbins became chair, Cian Ciaran deputy chair, Hedd Gwynfor secretary, and Gwyn Llewelyn treasurer, with additional non-portfolio members including Ifor ap Dafydd, Dilys Davies, Aran Jones, Bethan Siân Jones, Huw Marshall, Chantel Mathias, Mirain Llwyd Owen, and Julian Hughes Watts. The meeting also voted to restore previously suspended members, addressing earlier infighting criticized by branches like for hindering progress. Tensions escalated in amid rapid membership growth to approximately 18,000, fueled by heightened independence interest. Chair Siôn Jobbins resigned in July, followed by the entire in mid-August, citing intolerable harassment extending beyond that severely impacted members' mental . Interim chair Sarah Rees described the move as enabling a "clean break" for renewal, with third-party accountants appointed to manage limited operations pending an autumn EGM for new elections and constitutional revisions. These events stemmed from broader disputes over organizational direction and leadership. Post-2021 restructuring included the appointment of Gwern Gwynfil as CEO in 2022 to professionalize operations. However, following the 2022 AGM, the four officers—Iestyn ap Rhobert (chair), Rhydian Mehigan (communications), Lowri Gwilym (secretary), and Gwern Gwynfil (operations)—resigned their posts. Gwynfil's tenure saw claims of organizational success, including peak membership, but ended with his termination on December 18, 2023, officially for cost-saving amid financial strains, though he defended the period's achievements in membership expansion and campaigning. By November 2023, Barry Parkin was elected NGB chair, but dynamics deteriorated with co-options of directors like Cinzia Yates and Simon Hobson in mid-2023, later discharged amid complaints. An independent investigation by Elfyn Llwyd in October 2024 examined grievances against seven directors (Phyl Griffiths, , Naomi Hughes, Barry Parkin, Gaynor Jones, Elfed Williams, ), revealing trust breakdowns from opaque processes, disruptive conduct, confidential leaks, and paralysis in decision-making, including CEO termination disputes and legal fee concerns. The report recommended limiting co-options with rigorous vetting, mandatory training, improved member communication, and outsourcing disciplinary functions to independents to enhance stability. Ongoing challenges persisted into 2025, with elections held in January and an AGM in February, alongside records showing new appointments like a on March 8. Reports of further resignations in April highlighted recurring instability, though the continued activism. These repeated turnovers reflect persistent internal frictions over governance, transparency, and priorities, undermining sustained leadership cohesion despite periodic renewals.

Membership, Funding, and Operational Challenges

YesCymru's membership experienced rapid expansion during the , reaching a claimed peak of 18,000 in amid heightened online mobilization and public interest in . However, subsequent internal governance crises from to 2023, including disputes over leadership, disciplinary processes, and ideological positions on and issues, precipitated a sharp decline, with membership falling to approximately 4,000 by the end of 2022. By 2024, efforts to rebuild through elections and restructuring had not publicly restored prior levels, as ongoing reports of disarray continued to erode supporter confidence. The organization's funding model relies exclusively on membership subscriptions, small individual donations, and revenue from merchandise sales via its online shop, with all proceeds directed toward campaign activities. This approach avoids reliance on government or corporate grants, aligning with its non-partisan stance, but exposes it to volatility tied to membership fluctuations and lacks the diversified streams of larger political entities. Reports of unauthorized expenditures during the 2021–2023 crises, including unapproved spending amid board-level conflicts, strained these limited resources and fueled perceptions of financial mismanagement. Operational challenges have stemmed primarily from rapid, unmanaged growth outpacing organizational capacity, leading to public infighting, flawed disciplinary procedures, and leadership vacuums. An independent investigation in October 2024 highlighted deficiencies in the disciplinary panel's conduct, which exacerbated board-level divisions and deepened the crisis rather than resolving it. Leaked internal documents and videos from early 2024 revealed persistent chaos, including interpersonal conflicts and procedural lapses that diverted focus from campaigning to damage control. These issues, compounded by public resignations and online abuse directed at figures like clinical psychologist Dilys Davies during ideological clashes, have hindered effective coordination and sustained . Despite restructuring attempts by 2022, such as appointing a new chief executive prioritizing membership recovery, the interconnected nature of these problems— failures reinforcing financial and reputational harm—continues to impede operational stability.

Ideology and Positions

Core Advocacy for Independence

YesCymru's primary argument for emphasizes the inherent in the UK's centralized structure, where holds only 40 of 650 seats in the —approximately 6% of voting power—despite comprising 4.8% of the UK's population, rendering Welsh interests marginal in national decision-making dominated by English MPs. This lack of influence, they contend, perpetuates policy neglect, as evidenced by per capita infrastructure spending disparities, with receiving £100 per head compared to £2,500 in . would establish a fully sovereign with and no unelected upper chamber akin to the , enabling direct accountability to Welsh voters across all policy domains. Economically, YesCymru advocates for to harness ' untapped potential, including a reported £5 billion annual trade surplus and control over fiscal levers such as borrowing for , investments, and tailored taxation, which devolution's constraints—requiring consent for variations—currently prohibit. They draw comparisons to successful small nations like (population 370,000, high GDP per capita) and (GDP per head £50,000 versus ' £23,000), asserting that fosters agility in addressing brain drain, aging demographics via customized , and regional needs unmet by Westminster's indifference. Devolution since 1999 is critiqued as insufficient, failing to deliver prosperity or autonomy, thus necessitating full to prioritize Welsh economic diversification over -wide priorities. Culturally, independence is positioned as essential for safeguarding Welsh identity, , and institutions against assimilation pressures within the , including risks to distinct national sports teams like and , which could face integration into a '' framework. YesCymru further promotes a model post-independence, viewing the as an undemocratic relic tied to historical conquest—citing the 1282 execution of ap Gruffydd—and incompatible with , favoring decentralized governance inspired by Swiss cantons with community referenda over hereditary rule. Polling data, such as YouGov's 2023 findings showing only 28% support for the among 16-24-year-olds in , is invoked to underscore shifting public sentiment aligning with this vision. Overall, these arguments frame not merely as separation but as empowerment for , with YesCymru maintaining that even the pursuit of it could compel concessions, amplifying ' leverage.

Economic and Policy Proposals

YesCymru contends that would enable the nation to address its current fiscal deficit—estimated at £13.7 billion (17% of GDP) in official figures—by adopting tailored economic policies decoupled from -wide priorities, potentially reducing it to £2.6 billion (3.4% of GDP), a level comparable to the 's 2-5% and the average of 3.2%. The group argues that the deficit is inflated by underestimations of Welsh tax revenues, such as corporation tax (£2.3 billion versus the reported £1.306 billion in 2018-19), due to accounting practices assigning profits (e.g., from ) to . would allow reallocation of resources like contributions, potentially adding £600 million annually, and cuts to disproportionate expenditures, fostering growth akin to small independent nations like or . On , YesCymru outlines multiple options for an independent : maintaining the via formal union or unilateral adoption (sterlingization) for minimal disruption; introducing a Welsh pegged to the pound or with independent exchange rate controls; or adopting the upon EU membership. These choices prioritize monetary to support Welsh economic needs, contrasting with current constraints under policy. For trade, the organization proposes negotiating bespoke agreements, potentially via EFTA membership for access or full EU rejoining under Article 49 of the Lisbon Treaty, highlighting ' net £245 million EU budget benefit in 2016 and post-Brexit opportunities to prioritize local industries over interests. Specific policy levers include substantial reductions in defence spending—from £2.7 billion currently to £732 million annually—freeing funds for domestic priorities, and gaining control over Estate's £850 million in assets to invest in renewables and . YesCymru envisions independence unlocking a "flotilla effect," where small nations achieve up to 39% larger economies through agility, tax simplification, and investment, ultimately eradicating by expanding the tax base and improving GDP (£27,274 in 2022, already surpassing 165 countries). These proposals emphasize empirical comparisons to viable small states over reliance on subsidies, which YesCymru views as recycled Welsh taxes yielding poor returns, such as HS2 funding.

Stance on Broader Issues like and

YesCymru maintains no official position on membership or access for an independent , as the organization defines itself by a singular focus on advancing rather than ancillary policy matters. It asserts that such questions, including responses to Brexit's impacts, must ultimately be resolved through democratic processes by the after achieving . Nonetheless, YesCymru has commissioned and publicized polling data illustrating heightened support when paired with rejoining prospects; a survey released on April 4, 2025, found 51% of decided voters favoring in that scenario, compared to lower baseline figures without it. On devolution, YesCymru regards the post-1999 framework—expanded by the 2011 referendum—as fundamentally limited and precarious, granting powers over areas like and education but withholding control over , , , policing, and , thereby perpetuating Westminster's dominance. The group argues devolution offers no guaranteed permanence or economic uplift, citing persistent inequities such as unequal funding (e.g., HS2 exclusions) and vulnerability to UK government overrides, which underscore its inadequacy for true . While pushing for full as the sole remedy, YesCymru endorses specific devolutionary advances, including campaigns for transfer (delivering a June 19, 2025, letter to ) and justice/policing powers, framing these as pragmatic interim measures amid stalled progress.

Campaigns and Activities

Key Public Events and Marches

YesCymru co-organized its inaugural March for Independence on May 11, 2019, in Cardiff, drawing an estimated crowd of over 3,000 participants who marched from Cardiff City Hall. This event marked the beginning of a series of national demonstrations, often held in partnership with All Under One Banner Cymru (AUOBCymru), aimed at mobilizing public support for Welsh sovereignty. Subsequent marches expanded to other locations, with a notable gathering in on July 27, 2019, where over 8,000 attendees participated, highlighting growing momentum in . A third event in Merthyr Tudful later that year further demonstrated the campaign's reach into industrial valleys. These early 2019 marches established a pattern of street , featuring processions through city centers followed by rallies with speeches from independence advocates. Postponements due to the delayed further events until 2022, when a march on October 1 attracted organizer estimates of 10,000 participants, though local council assessments suggested a lower figure around 5,000. Similar large-scale demonstrations followed in (2022), (May 20, 2023), and Bangor (September 23, 2023, with 10,000-11,000 reported by organizers). In on June 22, 2024, thousands rallied again, underscoring sustained engagement. Recent marches include on April 27, 2025, where estimated 6,000-7,000 attendees, and on October 18, 2025, the tenth national event, with over 2,000 participants marching through the town. These gatherings typically involve banners, flags, and live performances at concluding rallies, serving as platforms to critique and promote economic , though attendance has varied by location and external factors like weather.

Digital Strategies and Grassroots Initiatives

YesCymru employs platforms, particularly (now X) and , as primary tools for mobilization and engagement, with guidelines mandating positive, non-partisan content focused exclusively on to foster broad support. These platforms have facilitated rapid membership growth, exemplified by an increase from 2,000 members in January 2020 to 17,000 by early 2021, driven by online recruitment during when physical events were restricted. The organization recommends bilingual posts, strategic use of hashtags such as #indyWales, and visuals to enhance visibility while prohibiting sarcasm, hostility, or digressions into unrelated issues like the or . Online campaigns include the "Say Yes" pledge, which has secured 36,062 signatures toward a target of 50,000 commitments to vote for in a , serving as a tool for building momentum and . YesCymru also promotes a UK urging to enable a , emphasizing democratic . These efforts align with a broader strategy leveraging for real-time updates, event promotion, and countering unionist narratives, as evidenced by academic analyses of Twitter's role in catalyzing the movement's expansion. Grassroots initiatives are structured through dozens of local groups, divided into accredited (requiring at least five members, regular meetings, and elected officers) and associate categories, enabling community-level campaigning tailored to regional contexts. Accredited groups receive up to £250 annually from the national body for activities such as printing banners, hosting events, or sponsoring local sports clubs, reinforcing volunteer-driven efforts without partisan affiliations. These branches, including YesCymru Caerdydd, YesCymru Rhydaman, and YesCymru Penfro, organize stalls, discussions, and smaller gatherings to promote independence locally, complementing national digital outreach by translating online momentum into on-the-ground action. This decentralized model underscores YesCymru's reliance on member-funded, bottom-up organization since its 2016 launch.

Public Opinion and Polling

Historical Support Levels

Public opinion polls on have consistently shown minority support since systematic polling began in the mid-2000s, typically ranging from 15% to 30% in surveys by established firms such as and ICM. A notable low occurred in the aftermath of the , when an ICM poll conducted for in September 2014 found just 3% favoring , the lowest recorded level at the time, amid a broader backlash against following Scotland's rejection of . Support rebounded modestly in subsequent years but remained below 30%. YouGov polls recorded 25% yes votes in July 2021, 24% in March 2022, and 27% in October 2022, with opposition consistently above 60% and undecideds around 10-12%. By September 2024, YouGov again reported 24% support for full independence, with 61% opposed. Temporary upticks have coincided with external events, including and the , where perceptions of divergent policy needs between and fueled discussion, though causal links remain debated and support did not exceed one-third in neutral polls. Polls commissioned by advocacy groups like YesCymru have occasionally shown higher figures, such as a April 2025 Redfield & Wilton Strategies survey indicating 41% support excluding don't knows, but these often employ referendum-style wording that critics argue overstates viability by minimizing undecided responses.

The same survey indicated stark age-based variations, with support exceeding 50% among those under 25 but dropping below 30% for over-65s. In contrast, a poll from September 2024 found only 24% backing full independence, with 61% opposed, reflecting more conservative estimates from polls not commissioned by independence advocates. Such discrepancies highlight methodological differences, including question wording and treatment of undecided respondents, which can inflate yes shares in pro-independence surveys by 10-15 percentage points compared to neutral ones.

Support for has trended upward from around 18-20% in early 2020s polls to the mid-20s to low-40s range by 2025, correlating with dissatisfaction over -wide policies like and fiscal constraints on devolved spending, though it remains a minority position unlikely to secure a majority without broader economic shifts. Recent data suggest stabilization or modest gains post-2024 election, with younger demographics driving potential long-term growth amid stagnant opposition from older voters.

Factors Influencing Public Sentiment

Support for , central to YesCymru's advocacy, has been elevated by generational shifts, with a April 2025 poll showing 72% backing among 25- to 34-year-olds compared to 80% opposition among those aged 65 and over. This demographic divide reflects broader trends where younger voters prioritize practical concerns over traditional , while older cohorts emphasize stability within the Union. Brexit has exerted dual influence, initially surging support by alienating pro-EU segments of the Welsh electorate— voted 52.5% Leave in 2016 but saw independence sentiment rise among Remainers—and fostering perceptions of detachment. However, it creates a strategic paradox: desires for EU realignment post-independence clash with ' economic interdependence on , potentially deterring voters wary of frictions or disruptions absent a UK-wide EU economic framework. The Welsh government's response, rated more favorably than the central effort under , enhanced trust in devolved institutions and indirectly bolstered self-rule arguments. Similarly, the 2014 Scottish referendum catalyzed discussions, inspiring Welsh activists despite its failure, alongside lingering historical resentments like the 1950s flooding of Tryweryn village for English needs, overriding local opposition. Economic apprehensions prominently restrain broader uptake, as Wales' net fiscal deficit stood at £15.3 billion—or 18.4% of —for the financial year ending March 2023, reliant on UK-wide transfers to fund public services. Independence would necessitate closing this gap through tax hikes, spending cuts, or growth unattained under , prompting warnings of ; Welsh Secretary argued in September 2025 that separation could exacerbate fiscal pressures amid UK-wide constraints like the two-child benefit cap and stagnant growth. Despite poverty rates—30% of children in relative as of 2024—driving some discontent with Westminster funding formulas, polls indicate independence ranks low as a voter priority, trailing issues like the and NHS. This calculus sustains support below 50%, even at recent peaks of 41% among decided voters in April 2025.

Reception

Domestic Support and Achievements

YesCymru has demonstrated domestic support through substantial grassroots membership expansion, particularly amid the . From approximately 2,000 members in early 2020, the organization grew to over 17,000 by February 2021 and peaked at around 18,000-19,000 shortly thereafter, positioning it as the second-largest political entity in at the time. This surge reflected heightened public engagement with amid perceived failures, including a reported 2,000 new sign-ups in a single day in November 2020. By late 2023, membership stood at about 6,500, following internal challenges that tempered earlier gains. Local government endorsements underscore further domestic backing. By August 2019, eleven town and community councils had formally supported Welsh independence, with Gwynedd County Council pioneering as the first county-level authority to endorse the goal in July of that year. In a notable policy success, YesCymru's "Wales Unites" campaign secured unanimous approval from all 22 Welsh councils for transferring Crown Estate control to Wales by June 2025, with Torfaen County Borough Council as the final holdout to affirm the motion. This cross-party local consensus highlighted the group's capacity to mobilize devolution-focused advocacy, contrasting with UK government resistance. Key achievements include elevating independence discourse, as claimed by former chief executive Gwern Gwynfil, who in December 2023 described YesCymru as outperforming all other Welsh political groups that year in visibility and impact. The organization has also amassed 36,062 signatures by mid-2025 for a public pledge to vote yes in an , advancing toward a 50,000-signature target. These efforts have fostered alliances, such as strengthened ties with the through joint events.

Criticisms from Unionists and Economists

Unionists contend that YesCymru's advocacy for overlooks ' structural economic dependence on the , particularly through fiscal transfers that cover a substantial between devolved spending and domestically raised revenues. Official estimates place this notional at £13.5 billion for 2019-20, representing approximately 18% of ' GDP, a figure derived from the Government's fiscal framework and highlighting the absence of equivalent revenue sources like that bolster Scotland's comparable calculations. Independence would necessitate closing this gap without UK-wide pooling, potentially requiring sharp tax hikes or service reductions, which unionists argue would exacerbate in regions already reliant on programs funded by the broader economy. Economists emphasize the formidable barriers to fiscal in an independent , given its small size, limited base, and exposure to disruptions with the residual market, which accounts for over 60% of Welsh exports. for Fiscal Studies has critiqued pro-independence platforms, such as Cymru's 2024 manifesto—which aligns with YesCymru's goals—for understating the "implications for public spending and taxation," implying unrealistic optimism about revenue generation without major structural reforms. Analyses from bodies like the Economics Observatory warn of heightened borrowing costs, currency volatility absent a , and the risk of economic shocks akin to those modeled for other small post-union states, where initial deficits often lead to prolonged . Prominent unionists have directed pointed rebukes at YesCymru's tactics and priorities. Welsh Secretary David Davies, a Conservative , described the group's sticker campaigns as "illegal" and ubiquitous defacement of public spaces, expressing frustration in 2021 that such actions prioritize symbolism over substantive policy debate. Similarly, Conservative MS Gareth Davies criticized a 2025 YesCymru march through economically deprived communities, arguing it diverts attention from urgent needs like and opportunities, which he attributes to the stability of UK-wide rather than separatist agitation. Labour unionist , Shadow Welsh Secretary, projected in 2025 that maintaining current public spending levels post-independence would demand over £11,000 in additional annual taxes per working-age adult, framing the proposal as a pathway to self-imposed fiscal hardship.

Internal Controversies and Scandals

In 2021, YesCymru faced a major internal crisis triggered by rapid membership growth from 2,500 in early 2020 to 18,000 by mid-year, which amplified disputes over its equalities policy beginning in May. The organization issued a statement in June condemning online abuse directed at its central committee, amid accusations of transphobia leveled against some members for views conflicting with transgender inclusion policies. Chair Siôn Jobbins resigned in July, acknowledging leadership failures in anticipating and managing heightened internal conflicts from the expansion, stating, "I should have foreseen that with a growth in membership there would be more disputes… I was at fault for not providing that leadership." This led to a vote of no confidence by grassroots groups, prompting the resignation of the entire central committee shortly thereafter. The turmoil continued into late 2023 with the abrupt dismissal of CEO Gwern Gwynfil via on December 20, citing "the needs of the business changing," followed by the board's removal of co-opted directors Cinzia Yates and Simon Hobson on December 8. A subsequent disciplinary panel, established by Complaints Officer David Hannington-Smith to investigate the seven directors involved, suspended them without hearing their defense and issued a biased "without " offer on January 17, 2024, to reinstate Yates and Hobson, which was rejected. The panel ignored legal advice affirming the dismissals' lawfulness, prompting the National Governing Body (NGB) to suspend Hannington-Smith and disband the panel, actions an independent investigation in October 2024 deemed to have deepened board-level paralysis and eroded trust. A leaked video of a board meeting exposed further rifts over legal fees accrued from Gwynfil's termination, with the disciplinary panel ruling the dismissal unlawful, fueling accusations of obstructive behavior against ousted directors who faced trolling and blocked access to organizational accounts. These events contributed to breakdowns, exemplified by YesCaerdydd—the organization's largest branch—considering dissolution in February 2024 after its chair, Iestyn ap Rhobert, resigned on February 14 amid concerns over and infighting. Current chair Elfed Williams faced criticism for the handling of these matters, highlighting persistent challenges in professionalizing operations post-2021.
