Leader of Reform UK in Wales stands down after arrest on suspicion of assault
Dan Thomas said he was reported to police and released without charge, and he will remain a Senedd member while Reform UK picks a new Welsh leader.
On Tuesday, Reform Wales leader Dan Thomas announced his resignation, citing 'personal reasons' after being reported to police over the weekend and released without charge. He will continue serving his Casnewydd Islwyn constituents.
Under Thomas's leadership, Reform Wales expanded from zero to 34 elected members, establishing the party as a major opposition group in the Senedd after his 2025 selection by Nigel Farage. This rapid growth created significant organizational expectations.
Thomas was absent from Tuesday's First Minister's Questions, the first Senedd session following the summer recess, where Reform deputy leader Helen Jenner stood in for him in the chamber.
Simultaneously, Pen-y-Bont Bro Morgannwg representative Sarah Cooper-Lesadd defected from Reform to Plaid Cymru on the same day, compounding organizational instability as the party seeks a successor leader.
Formerly a Conservative who served on Barnet London Borough Council from 2006 to 2025, Thomas pledged to support his successor while maintaining his Casnewydd Islwyn constituency duties.
