Nigel Farage's Reform UK is a "one-man personality cult" with no serious solutions for Wales, Tory Senedd leader Darren Millar said on Saturday.
The politician used a speech at Welsh Conservative conference in Llangollen to put "clear blue water" between his party and Reform.
Millar claimed that Reform UK have "utterly failed" to offer any "real, serious, costed or deliverable solutions".
Reform has performed better than the Conservatives in recent polling for the next Senedd election in May 2026, competing for first place with Plaid Cymru and Labour.
Opinion polls have suggested a four way split among most voters, with the latest poll indicating that Plaid Cymru had the most support at 30%, with Reform on 25%, Labour 18% and the Tories 13%.
Reform came second in 13 Welsh seats at the last general election but failed to win any MPs.
It has yet to pick someone to be the party's main spokesperson or leader, and has not announced who might stand for the party.
