Nigel Farage has said Reform UK would be willing to work with any other party to form a government in Wales next year.
Reform is hoping to win its first Senedd seats at the Welsh Parliament elections in May 2026, with recent polling suggesting support for the party is closely behind Labour, and neck and neck with Plaid Cymru.
Farage told BBC Wales that he was open to doing a deal because the Senedd's new voting system will mean "it's not going to be easy" to win an overall majority.
The party leader also refused to be drawn on whether Reform UK would appoint a new Welsh leader prior to the Senedd elections, replying: "Give me time".
Meanwhile UK Conservative leader Kemi Badenoch has refused to be drawn on whether the Tories would enter a post-electoral pact with Farage's party.
Reform failed to win any Senedd members at the last vote in 2021, but came second in 13 Welsh constituencies at the general election last summer.
Polling by Survation conducted in March and April put Labour on 27%, and Plaid Cymru and Reform on 24% each, with the Tories behind on 15%.
The new voting system will elect a larger Senedd with 96 seats instead of the current 60, and will use a list system that aims to better reflect how the public voted.
While Labour has never held a majority in the Welsh Parliament, other parties will likely hold leverage than before if the election result reflects the state of the polls.
