By-election wins, surging polls and a reshaped Senedd system fuel Reform’s rapid rise

REFORM UK is no longer a fringe force in Welsh politics. With polling surges, a local by-election victory, and a favourable new voting system set to reshape the Senedd in 2026, the party is rapidly gaining traction—and some believe traditional parties are failing to grasp the scale of its momentum.

A May 2025 YouGov/ITV Wales poll placed Reform UK second in Wales with 25% of the projected vote—just behind Plaid Cymru on 30%, and well ahead of Labour on 18%. That number is a stark decline: Labour won a 36% regional vote in 2021, making its current standing half of its previous share.

Disillusionment among Labour voters is evident. Only 40% of those who backed Labour in the 2024 UK general election currently intend to do so for the next Senedd election, with substantial numbers shifting to Plaid Cymru (24%), Liberal Democrats (8%), Reform UK (5%), and Greens (4%).

Local Shifts and Breakthroughs

On May 29, Reform achieved a breakthrough when Michelle Beer won the Lliedi ward by-election in Llanelli—becoming the party’s first elected councillor in Carmarthenshire. In a ward long seen as Labour territory, the win signalled a dramatic shift.

That momentum continued days earlier in Pembrokeshire, when Scott Thorley, a former Reform candidate, was co-opted onto Haverfordwest Town Council. His appointment ignited local opposition from campaigners concerned about Reform’s stance on the Anti-racist Wales Action Plan (AWAP).

The AWAP Dispute and Political Fallout

Reform UK has openly opposed the AWAP, criticising its focus on identity-based policies, such as increased grants for ethnic minority student teachers and cultural accommodation in public spaces. Critics say these measures undermine meritocracy and divide communities.

After Thorley’s co-option, political graffiti at Withybush Retail Park—featuring slogans like “VOTE REFORM” and “GOD SAVE US”—only intensified debate. Thorley swiftly condemned the graffiti, calling it “vandalism, plain and simple,” and defended the party’s intentions.

“As I have been invited to help on the anti‑racist action plan … I’m really confused by their comments. … Politics is about talking and helping people. … stop acting like stroppy teenagers.”
— Scott Thorley, Town Councillor, speaking to The Pembrokeshire Herald

Leadership turbulence and image strategy
Reform has also faced internal turbulence. Chairman Zia Yusuf, a practising Muslim, resigned on June 5, citing exhaustion and policy disagreements—particularly over a proposed burka ban—but reversed that decision just two days later. He returned to lead a new strategy unit focused on governance, fundraising, and outreach. His continued presence is seen as key to diversifying Reform’s image and countering claims of intolerance.

Farage, culture wars, and language policy

At the helm, Nigel Farage has declared Wales a top priority, urging voters to back ‘real change’. He promised to scrap policies such as the 20mph default speed limit, the “Nation of Sanctuary” scheme, and the Welsh Government’s goal of one million Welsh speakers by 2050—labelled by Reform as cultural overreach.

While Farage offered limited detail on his opposition to the Welsh-language target, his position aligns with a broader opposition to identity-based policymaking.

Even Plaid warns: “Reform could win”

The growing momentum behind Reform UK has not gone unnoticed by its political opponents. Speaking at the party’s Spring conference in Llandudno, Plaid Cymru’s Westminster leader Liz Saville Roberts warned party members that Reform could become the largest party in the Senedd if they are not taken seriously.

“If we—Plaid Cymru—do not provide solutions to Labour’s failings, there is something worse waiting in the wings to take their place,” she said.

“If we do not take this threat seriously, they could become the biggest party in the Senedd—our national parliament. If that happens, it would be a disaster for Wales. This must galvanise us.”

Saville Roberts accused Reform of thriving on division and warned that the party would seek to privatise the NHS, strip away workers’ rights, and undermine Welsh identity and the language.

Pushback from Welsh leaders

Welsh Labour’s First Minister Mark Drakeford condemned the proposal to remove the language goal, asserting that the Welsh language “belongs to us all” and should be defended from external political interference. Plaid Cymru MS Llŷr Gruffydd dismissed Farage’s claims as “empty soundbites” and accused him of “railing against Welsh culture and identity” to advance his own agenda.

Labour’s collapse in its historical heartlands is resonating at the grassroots. The Barn Cymru poll confirms their support is now the lowest since devolution began, under 20%. Meanwhile, local expressions of discontent are growing, with public services—especially in rural and post-industrial areas—seen as deteriorating, boosting calls for change.

A once-unshakeable Labour dominance is cracking. With Plaid Cymru and Reform UK capitalising on voter fatigue, policy stumbles, and identity politics backlash, Wales is entering a new era of volatility. As the Senedd moves to proportional representation, the question isn’t whether Reform will take seats, but whether Labour has already ceded too much ground.
