Reform UK Makes Turbulent Start as Official Opposition in Welsh Parliament

Reform UK has made a dramatic start as the official opposition in the Welsh Parliament, with heated debates, emotional exchanges, walkouts, and voting mistakes drawing attention during its first weeks in the Senedd.

The party became the official opposition after finishing second in Wales' historic May 2026 election. Although Plaid Cymru ended Labour's century-long dominance by winning the election, Reform UK achieved its strongest result in Wales, increasing its vote share from 1% in 2021 to 29% in 2026.

With more than one-third of the seats in the newly expanded Senedd, Reform now has its largest political presence ever in Wales.

Reform Wales leader Dan Thomas defended his party's approach, saying it is expected that new political voices challenging long-standing views will face criticism from the political establishment.

One of the biggest controversies involved Reform Senedd member Joe Martins during First Minister's Questions. Martins compared Ukrainian and Sudanese refugees and claimed that only Sudanese refugees commit violent crimes. He then asked First Minister Rhun ap Iorwerth how he would prevent what he called "the next inevitable attack."

The remarks shocked many members in the chamber and people watching from the public gallery.

Labour Senedd member Shav Taj became emotional while responding. She spoke about her own family's immigration experience and criticized Martins for linking immigration with Wales' Nation of Sanctuary programme.

She described the comments as shocking and said the Senedd should remain a respectful workplace where members use appropriate parliamentary language.

The following day, Martins again sparked criticism after claiming Welsh students struggle to read and suggesting that Indian nurses were taking jobs from local workers. His remarks prompted some members from Plaid Cymru, Labour, and the Green Party to leave the chamber in protest.

The Senedd's presiding officer later formally rebuked Martins. However, Reform's chief whip, Llŷr Powell, defended his colleague and said other parties would have to "get used to" Reform's style of politics.

Dan Thomas said Reform members follow Senedd rules and focus on presenting evidence-based arguments on behalf of their voters. He added that the party would continue raising issues that it believes have not been properly represented in Welsh politics.

Political observers have also noted that most Reform representatives are serving in the Senedd for the first time and are still adapting to parliamentary procedures.

The party also faced embarrassment after several of its own members accidentally supported a Plaid Cymru childcare motion that highlighted Reform's lack of childcare commitments in its election manifesto. Political commentator Will Hayward suggested some members may not have understood the motion or simply voted incorrectly.

Plaid Cymru now leads a minority government and must secure support from other parties to pass key legislation, including an upcoming supplementary budget. Reform has so far shown little sign that it intends to cooperate.

The party will also chair five of the Senedd's 13 committees, including the Climate Change, Environment, Sustainability and Rural Affairs Committee. Critics have questioned how Reform's climate policies will influence the committee's work, given the party's opposition to net zero policies.

Professor Laura McAllister of Cardiff University said Reform faces pressure to demonstrate discipline if it hopes to convince voters that it is ready for greater political responsibility. She noted that party leader Nigel Farage remains the key decision-maker and understands that disorder in Wales could affect Reform's wider political ambitions.

Despite the controversies, Reform secured cross-party support for a proposal to introduce a statutory lobbying register. However, the party has also scheduled a debate on Wales' Nation of Sanctuary programme, a move that many lawmakers expect will trigger another heated political confrontation.

Plaid Cymru Senedd member Peredur Owen Griffiths said the atmosphere in the Welsh Parliament has changed significantly since the election. He said it remains unclear whether Reform is still adjusting to parliamentary standards or deliberately choosing a more confrontational approach, adding that many lawmakers are concerned if the current trend continues.
