UK Conservative leader Kemi Badenoch and her Senedd leader Darren Millar have declined to rule out deals with Plaid Cymru and Reform after next year's election in Wales.
On current projections, it is likely politicians of different parties will need to work together to form the next Welsh government, with a majority difficult to obtain.
On the first day of his party's Welsh conference in Llangollen, Senedd Tory leader Darren Millar has said his party was willing to work with "anybody" to get Labour out of power.
Kemi Badenoch, who has ruled out working Reform at a UK level, admitted it was a "reality" that post-election talks may need to happen but said the conversation was a "distraction".
The Conservatives have been polling in fourth place behind Labour, Reform UK and Plaid Cymru ahead of the election in Wales next May and lost all their Welsh MPs at the last general election.
Millar described his party, which has 16 seats in the Welsh Parliament, as a "government in waiting" while Badenoch called on members to "fight back" against Plaid Cymru and Reform.
It is unlikely Labour would ever work with the Conservatives or Reform. Plaid Cymru has ruled out working with Reform but not the Tories or Labour.
