Dan Thomas, the leader of Reform UK in Wales, has stepped down after being arrested and bailed on suspicion of assault. Gwent police confirmed that a 45-year-old man from the Aberbargoed area was arrested on Sunday, 13 September, on suspicion of assault and has since been bailed pending further inquiries.
Mr Thomas, a former Tory councillor, was announced as Reform UK’s Welsh leader by Nigel Farage in February 2026. He was subsequently elected to the Senedd as leader of the opposition in May's election.
In a statement released on Tuesday afternoon, Mr Thomas said he was reported to the police over the weekend and released without charge. He stated: “I stress that I have done nothing wrong, but I do not want the coming headlines to be a distraction from the fantastic work our Senedd team is doing in holding this government to account.”
