Conservative leader Kemi Badenoch has not ruled out a post-election deal with Reform in Wales after the country goes to the polls next May.
Polling ahead of the Welsh Parliament election suggests Reform is likely to finish ahead of the Conservatives in an expanded 96-member Senedd.
But speaking on a visit to Monmouth, Badenoch said any decision on whether the two parties could join forces to form a government would be down to Darren Millar, the Tory leader in Cardiff Bay.
A spokesperson for Reform UK Wales responded to the idea by saying the Senedd election was a "two-horse race between Reform and Plaid Cymru".
