Wales (Wales Times) September 21, 2026 — Reform UK leader Nigel Farage named Helen Jenner as the party’s new leader in Wales, following the resignation of Dan Thomas after his arrest on suspicion of assault and controlling or coercive behaviour. The announcement took place on the steps of the Senedd in Cardiff Bay, where Jenner appeared alongside Farage.

The change gives Reform UK a new leader in Wales less than a week after Thomas stood down from the post. Thomas remains a Member of the Senedd, but he will no longer lead the party’s Welsh group.

According to The News International, the leadership transition followed Thomas’s arrest by Gwent Police and his subsequent release on police bail pending further inquiries. The report also said Thomas had maintained his innocence and had indicated that the circumstances made his continuation as leader untenable.

The appointment marks a significant change for Reform UK in Wales because Thomas had led the party to become the largest opposition group in the Welsh Parliament after the May Senedd elections.

Why did Dan Thomas leave the leadership?

Dan Thomas announced that he was stepping down as Reform UK’s Welsh leader after police confirmed that he had been arrested. The allegations relate to assault and controlling or coercive behaviour.

The exact circumstances surrounding the investigation have not been publicly detailed by Gwent Police. Thomas has not been charged, and he has denied wrongdoing.

As reported by ITV News Wales, Thomas said in a statement that he had been “reported to the police” and was later released without charge. He also said he had “done nothing wrong”.

The distinction between arrest and charge remains important. An arrest does not establish that an offence has been committed, while an investigation can continue without charges being brought. Thomas’s departure from the leadership was therefore a political decision rather than the result of a criminal conviction.

Thomas said he was standing down for “personal reasons”. His resignation created an immediate vacancy at the top of Reform UK Wales and left the party needing to appoint a new leader during the early stages of the Senedd term.

How was Helen Jenner selected?

Helen Jenner was chosen through an internal contest involving Reform UK Members of the Senedd.

According to reporting cited by The News International and attributed to Welsh politics commentator Will Hayward, Jenner faced Jason O’Connell in the contest. Jenner reportedly secured 17 votes, while O’Connell received 15.

The result indicates that the appointment was not unanimous. The close vote also suggests that Reform UK’s Welsh Senedd group had competing preferences about who should take over from Thomas.

The contest took place against the backdrop of a rapidly changing political situation. Jenner had already become the party’s interim leader after Thomas resigned, making her the most visible figure available to take over permanently.

BBC reporting also identified O’Connell as the colleague who challenged Jenner, despite not initially being expected to enter the contest. The result allowed Jenner to move from deputy leader to the formal leadership position.

Who is Helen Jenner?

Helen Jenner is the Senedd Member for Bangor Conwy Môn in north Wales. She represents the same constituency area as First Minister Rhun ap Iorwerth.

ITV News Wales reported that Jenner grew up on Anglesey and attended university in Bangor. Before entering politics, she worked as a teacher for 15 years.

Since being elected in the May Senedd election, Jenner has served as Reform UK’s shadow cabinet minister for education and the Welsh language. She previously held the role of deputy leader of Reform UK in Wales.

Jenner also has a political history linked to parties associated with Nigel Farage. She previously stood for the Brexit Party at the 2019 UK general election and had been a member of UKIP when Farage led the party.

Her experience in education and Welsh-language policy is likely to be significant as she takes responsibility for a party seeking to expand its influence across Wales.

Jenner also stepped into a prominent parliamentary role during the leadership uncertainty. She stood in for Thomas during First Minister’s Questions shortly before his resignation, giving her an early opportunity to represent the party in the Senedd.

What did Helen Jenner say after her appointment?

After being announced as leader, Jenner said she was “thrilled” to take charge of Reform UK in Wales.

As reported by ITV News Wales, she said Welsh voters had delivered a clear mandate in May to “smash the establishment” and bring “common sense to Cardiff Bay”.

Jenner added that Reform UK had been pursuing that objective “week in, week out” and would continue until Wales achieved what she described as “real change”.

Her comments placed the focus on Reform UK’s political programme rather than the circumstances surrounding Thomas’s resignation. They also reflected the party’s wider campaign language, which presents it as an alternative to the established Welsh political parties.

Jenner will now be responsible for turning that message into parliamentary activity while managing the internal pressures created by the leadership contest.

What did Nigel Farage say about the leadership change?

Nigel Farage presented Jenner as a strong and trusted figure for Reform UK in Wales.

According to The News International, Farage described the upheaval as a “bump in the road” and praised Jenner as a “tenacious” campaigner. He also expressed sympathy for Thomas, referring to the former leader’s “personal difficulties”.

Farage said Thomas had been doing a “brilliant job” before the controversy, but acknowledged that he could no longer remain in the leadership role.

The comments appeared to balance two objectives. Farage sought to support Jenner’s appointment while avoiding a direct judgment on the police investigation involving Thomas. At the same time, his praise for Thomas indicated that the party had not treated the former leader’s resignation as a finding of guilt.

The decision to announce Jenner alongside Farage also underlined the importance of the Welsh leadership role to Reform UK’s national organisation.

What challenges face the new Reform UK Wales leader?

Jenner’s immediate challenge will be to restore stability within the Reform UK group at the Senedd.

The internal vote was close, with the reported 17-15 result showing that the group was divided over the leadership choice. The News International reported that sources close to the Reform group feared the party could face another leadership contest within six months.

The party has also experienced broader disruption. BBC reporting described the preceding period as a turbulent week involving Thomas’s arrest, his resignation and uncertainty over the party’s next leader.

The new leader must therefore manage both public communications and internal relationships. The next priority will be maintaining a united opposition group in the Welsh Parliament and ensuring that members present a consistent position on key policy issues.

Jenner must also appoint or support a replacement deputy leader. BBC reporting said Farage indicated that a vote would take place on Tuesday to select a new deputy for Wales.

That decision will be closely watched because the deputy position will help determine how Reform UK distributes responsibilities inside its Senedd group.

How important is the role in the Senedd?

The Welsh Reform UK leader also leads the party’s group in the Senedd, making the post more than an internal party position.

Reform UK emerged from the May elections as the largest opposition group in the Welsh Parliament, according to The News International. That status gives the party a prominent role in challenging the Welsh Government and scrutinising the first minister.

The leadership change therefore affects the organisation of opposition politics in Wales. Jenner will be expected to coordinate the group’s response to government policy, represent Reform UK publicly and maintain its profile ahead of future political contests.

Her background in education and the Welsh language may also shape the areas on which she places emphasis. However, her first responsibility will be to establish authority within the group after a closely fought leadership election.

How have other Welsh parties responded?

The leadership change has provided an opportunity for rival parties to question Reform UK’s internal stability.

The News International reported that Welsh Labour and Plaid Cymru had seized on the controversy surrounding Thomas’s resignation. Their criticism focuses on the speed of the leadership change and the political uncertainty within Reform UK Wales.

The opposition parties are likely to use the episode to challenge Reform UK’s readiness to operate as Wales’s largest opposition group. Reform UK, meanwhile, will seek to move attention towards its policy agenda and the electoral mandate it says it received in May.

The political dispute is expected to continue in the Senedd, where Jenner’s leadership will be tested through debates, First Minister’s Questions and scrutiny of the Welsh Government.

What happens next for Reform UK in Wales?

The immediate next step is expected to be the selection of a new deputy leader to replace Jenner.

Once that position is filled, Reform UK will need to settle its internal structure and decide how responsibility is shared among its Senedd members. The party will also have to demonstrate that the leadership transition has not weakened its ability to act as the largest opposition group.

Thomas’s future remains separate from the leadership contest. He continues to be a Member of the Senedd, while the police investigation remains ongoing. No conclusion about the allegations can be drawn unless and until the relevant authorities take further action.

Jenner will also need to maintain the party’s public profile across Wales. Her leadership statement focused on challenging the establishment and pursuing change in Cardiff Bay, but voters will judge the party on how effectively it turns those commitments into parliamentary work.

Background to Reform UK’s leadership change in Wales

Dan Thomas became a central figure in Reform UK’s Welsh operation after the May Senedd elections, when the party became the largest opposition group in the Welsh Parliament.

Thomas later resigned after Gwent Police confirmed his arrest on suspicion of assault and controlling or coercive behaviour. He said he had done nothing wrong and was released without charge, according to ITV News Wales.

Helen Jenner, who had served as Thomas’s deputy, took on interim responsibilities before winning the internal leadership contest. Her reported victory over Jason O’Connell was decided by 17 votes to 15.

The appointment followed a week of uncertainty for the party, during which Jenner deputised for Thomas at First Minister’s Questions and became the expected successor. Farage’s appearance in Cardiff confirmed that Reform UK had chosen her to lead the Welsh party and its Senedd group.

How could Helen Jenner’s appointment affect Welsh voters?

Helen Jenner’s appointment could give Welsh voters a clearer indication of Reform UK’s direction in the Senedd, but its impact will depend on whether she can unite the party’s members and maintain a consistent policy agenda.

For Reform UK supporters, the change may provide a way to move beyond the controversy surrounding Thomas and return attention to issues such as education, the Welsh language, public services and opposition to the established parties.

For other voters, the close internal contest and the circumstances of Thomas’s resignation may raise questions about the party’s stability. Those concerns could influence how Reform UK is viewed as it develops its role as the largest opposition group.

The most immediate effect will be visible inside the Senedd. Jenner will need to establish authority, appoint a deputy and coordinate the party’s response to the Welsh Government. If she succeeds, Reform UK may be able to preserve its electoral momentum; if divisions continue, the leadership change could remain a source of political uncertainty.
