Reform UK Makes Dramatic First Impression in Senedd Opposition Role

The arrival of Reform UK as the official opposition in the Welsh Parliament has transformed the political atmosphere in Cardiff Bay. After the 2026 Senedd election, Reform emerged as the second-largest political force in Wales, winning 34 of the chamber’s 96 seats. Plaid Cymru, with 43 seats, became the largest party and formed a minority government. Labour, which had dominated Welsh politics for decades, suffered a historic defeat.

For Reform UK, the result was a remarkable breakthrough. The party had won only about 1% of the Welsh vote in 2021, but its share rose to approximately 29% in 2026. Although Nigel Farage had hoped Reform would become the largest party, finishing second still gave the party something it had never possessed before: a huge parliamentary platform from which to challenge a government directly.

However, Reform’s first weeks in opposition have been anything but conventional. Instead of quietly establishing itself within the Senedd’s parliamentary routines, several of its politicians have immediately attracted controversy. Emotional exchanges, walkouts, disputed statements and even votes against their own party have created an image of a political group still learning how to operate inside a parliamentary institution.

The most controversial incident involved Joe Martins, a Reform Member of the Senedd representing Caerdydd Penarth. During First Minister’s Questions, Martins made controversial remarks about Ukrainian and Sudanese refugees and linked immigration with the possibility of future attacks. His comments caused visible distress in the chamber. Labour MS Shav Taj struggled to hold back tears while responding, drawing on her own family’s experience of immigration.

The incident was significant because it immediately established one of the central questions surrounding Reform’s role in Wales: can a party built around confrontational political rhetoric adapt that style to the responsibilities of parliamentary opposition?

Reform’s supporters would argue that confrontation is precisely what voters elected them to provide. The party’s Welsh leader, Dan Thomas, has said that Reform intends to challenge established political assumptions and raise issues that, in its view, have not been properly represented in the Senedd. From this perspective, criticism from other politicians and the media is evidence that Reform is disrupting an established political consensus.

There is some truth in this argument. Opposition parties are not supposed to make governments comfortable. Their role is to scrutinise ministers, expose weaknesses and offer alternative policies. Reform’s presence has certainly increased political pressure on the new Plaid Cymru government.

But parliamentary politics requires more than the ability to attract attention. An effective opposition must understand procedure, develop credible policies, build alliances and persuade other parties to support its proposals. It must also distinguish between strong criticism and statements that damage its own credibility.

This distinction became particularly important when Martins made further controversial comments during a debate the following day. He claimed that Welsh students were unable to read and suggested that Indian nurses were taking jobs from Welsh workers. The remarks prompted several Labour, Plaid Cymru and Green members to walk out of the chamber. Martins was subsequently rebuked by the Senedd’s presiding officer.

Reform’s response was unapologetic. Its chief whip, Llŷr Powell, reportedly told the BBC that the other members of the Senedd should “get used to it”, describing the party’s approach as the “new norm”. The message was clear: Reform had no intention of adopting the political style of the parties that had dominated Welsh politics for generations.

This strategy has obvious political advantages. Reform has built its electoral success by presenting itself as an outsider challenging the political establishment. Its supporters may appreciate politicians who refuse to follow traditional conventions and who speak in language they consider more direct.

Yet there is a danger that permanent confrontation becomes a substitute for effective opposition. Shav Taj described the Senedd as a “circus” and argued that some Reform politicians appeared to be seeking attention through provocative statements and social-media-friendly moments. Her criticism highlights the central dilemma facing Reform: attracting attention is relatively easy, but converting attention into political influence is much harder.

The party’s supporters could respond that media attention is itself a form of political influence. In modern politics, a controversial parliamentary exchange can reach hundreds of thousands of people through television clips and social media. Reform has demonstrated considerable skill in exploiting this environment.

Nevertheless, Wales is not simply another stage for national political campaigning. The Senedd has specific responsibilities involving healthcare, education, transport, housing, agriculture and other devolved areas. Immigration, for example, is primarily controlled by Westminster rather than the Welsh Parliament. This creates a potential problem for Reform because some of its most popular national political themes do not directly fall within the Senedd’s powers.

The party must therefore demonstrate that it understands the difference between Westminster politics and Welsh devolution. If its representatives spend too much time discussing issues over which the Senedd has limited control, opponents can accuse them of campaigning rather than governing or scrutinising the Welsh Government.

At the same time, Reform has shown that it can engage successfully with devolved policy. One of its early successes was a motion calling for a statutory register of lobbyists in Wales. The proposal received cross-party support and passed in the Senedd. Reform politicians presented this as evidence that they could achieve practical policy changes rather than simply generate controversy.

This example is important because it demonstrates another possible future for Reform in Wales. The party does not have to choose between being confrontational and being constructive. It can attack the government strongly on some issues while also building cross-party support for policies that other parties can accept.

Indeed, the structure of the Senedd makes cooperation particularly important. Plaid Cymru holds 43 of the 96 seats and therefore does not have a majority. The government needs support from other parties to pass budgets and important legislation. Reform, with 34 seats, is potentially powerful enough to influence the outcome of major votes.

This became clear when the Welsh Government lost a crucial supplementary budget vote in July. Reform, Labour and the Conservatives all voted against the Plaid Cymru government’s proposals, producing a 49-44 defeat. The result demonstrated that the minority government cannot simply assume that its policies will pass and that Reform has the ability to contribute to significant parliamentary defeats.

For Reform, this represents a much more meaningful form of opposition than provocative speeches. If the party can use its 34 seats strategically to force changes to government policy, it will demonstrate genuine parliamentary influence.

The question is whether it can develop the discipline required to do so consistently.

There have already been signs of organisational difficulties. Some Reform members voted against their own party during a debate concerning Plaid Cymru’s childcare proposals. Approximately one-third of Reform’s members supported a motion containing an amendment that explicitly noted Reform’s lack of Welsh childcare commitments. Political observers suggested that some members may not have understood the motion or may simply have voted incorrectly.

Such mistakes are understandable for a newly formed parliamentary group. Almost all Reform MSs are newcomers to the Senedd, with only two having previous experience as members through Conservative defections. They are learning parliamentary procedure while simultaneously trying to establish themselves as the official opposition.

But this is precisely why the first months are so important. Reform has moved rapidly from being an insurgent political movement to holding more than a third of the Welsh Parliament’s seats. That creates expectations that its members will behave like serious legislators.

The party itself insists that it is capable of doing so. Dan Thomas has argued that Reform operates within the rules of the Senedd and is committed to making evidence-based arguments on behalf of Welsh voters. He has described the party’s approach as constructive while maintaining that it will challenge issues that other politicians have avoided.

Reform has also been given substantial institutional responsibilities. Its members will chair five of the Senedd’s 13 committees, including the committee dealing with climate change, environment, sustainability and rural affairs. This gives the party an opportunity to demonstrate that it can scrutinise government policy in detail rather than simply make speeches in the main chamber.

Committee leadership may ultimately be more important to Reform’s long-term reputation than dramatic exchanges during First Minister’s Questions. Committees require preparation, evidence, detailed questioning and cooperation. They provide a direct test of whether Reform politicians can master the technical side of parliamentary politics.

Climate policy could be particularly challenging. Reform has opposed aspects of the UK’s net-zero agenda, while some of its politicians have expressed outright scepticism about climate change. Holding the chair of a committee dealing with climate and environmental policy will therefore place the party under intense scrutiny.

The party will also face a broader political test. Its success in the Senedd election demonstrated that many Welsh voters wanted something different from the traditional political parties. Reform’s 29% vote share cannot simply be dismissed as an accident. However, maintaining that support will require more than opposition to Labour or Plaid Cymru.

Voters will eventually judge Reform according to what it actually achieves. Can it improve public services? Can it influence healthcare policy? Can it offer credible ideas for the Welsh economy? Can it represent rural communities and farmers effectively? Can it scrutinise government spending without simply opposing everything?

These questions matter because Reform’s ultimate ambitions extend beyond Wales. Nigel Farage wants Reform UK to become a serious governing force across Britain. The Welsh Senedd therefore represents a kind of political laboratory. If Reform can demonstrate that its representatives are capable of governing responsibly and working within institutions, it can use that experience to strengthen its argument that the party is ready for Westminster.

Conversely, if the Welsh group becomes associated primarily with disorder, offensive rhetoric and internal confusion, the consequences could extend beyond Cardiff Bay. Critics would argue that the behaviour of Reform’s Welsh representatives offers a preview of what a Reform government might look like at Westminster.

This is why Professor Laura McAllister has argued that Reform’s performance in Wales matters to Farage’s wider ambitions. A populist insurgent party can benefit from disruption when it is outside government. But voters may demand something different when considering whether that party should actually govern. They want discipline, competence and seriousness as well as strong rhetoric.

There is therefore a paradox at the heart of Reform’s success. Its aggressive political style helped it win support, but the same style could become a weakness once it assumes institutional responsibility.

The party has three possible paths. It could continue to maximise confrontation and media attention, maintaining the outsider identity that helped it succeed electorally. It could move towards a more conventional opposition style, focusing on detailed policy and parliamentary procedure. Or it could attempt a combination of both: using strong rhetoric to mobilise supporters while becoming increasingly disciplined in parliamentary negotiations and committee work.

The third option may be the most effective. Reform does not need to become indistinguishable from Labour, Plaid Cymru or the Conservatives. Its political appeal depends partly on being different. But being different does not necessarily mean being chaotic.

Indeed, Reform’s strongest moments so far have arguably been those in which it has turned its political priorities into concrete parliamentary proposals. The lobbying register is one example. Its involvement in debates over Welsh farming and bovine tuberculosis could become another. These are areas where the party can demonstrate that it understands Welsh concerns while offering specific policy alternatives.

Ultimately, the first impression created by Reform in the Senedd has been dramatic because the party itself represents a dramatic change in Welsh politics. Labour’s century-long dominance has ended, Plaid Cymru is governing for the first time, and Reform has become the largest opposition group. The political rules of Wales have changed significantly.

The early controversies should therefore be viewed in context. A few weeks or even a few months are not enough to determine whether Reform will become an effective opposition. The new Senedd is itself adapting to an unprecedented political configuration, and Reform’s members are learning their roles at the same time.

What can already be said is that Reform has succeeded in making itself impossible to ignore. It has forced debates about immigration, national identity, public services, government spending and Wales’s relationship with the wider UK. It has also demonstrated that it can sometimes secure cross-party support for specific proposals and can influence important votes.

The challenge now is to decide what kind of opposition it wants to be.

If Reform continues to rely primarily on provocative statements and political theatre, it may energise its existing supporters but struggle to convince undecided voters that it is ready for government. If it combines its distinctive political message with parliamentary discipline, detailed policy and effective scrutiny, it could transform its large electoral breakthrough into lasting political influence.

For Wales, the arrival of Reform is already changing the character of the Senedd. For Reform itself, however, the real test has only just begun. Winning 34 seats was an extraordinary achievement. Using those seats responsibly and effectively will be much harder.

The party has arrived in the Senedd with enormous political momentum. Whether that momentum becomes a durable force for change or descends into repeated controversy will depend on what its members do next. The first impression has certainly been dramatic. The next task is to prove that Reform can turn drama into results.
