PLAID CYMRU could be forced to share power with Labour in Wales to avoid the far-right gaining power, a poll has shown.

The survey, from More in Common, puts Plaid narrowly ahead of Reform in the Welsh Parliament election on May 7, but it may fall short of a majority and need a coalition with Welsh Labour to govern.

More in Common’s poll of this Senedd election predicts Plaid Cymru will win 30 seats, Reform 28 and Welsh Labour 24.

The Welsh Greens, forecast to win four seats and the Welsh Liberal Democrats, forecast to win three, have indicated they are open to negotiations with Plaid.

But an agreement with Labour could be the only viable route to government, with a total of 49 seats needed for a majority.

The two parties have been in coalition before, but Plaid withdrew from its most recent partnership in 2024 and has centred its campaign around replacing its rival.

The survey shows Reform is set to make significant gains across Wales, with some of its strongest performances in the South Wales Valleys.

By contrast, the Welsh Conservatives are projected to be pushed into fourth place, winning just seven seats.

More in Common executive director Luke Tryl said: “Having governed in Wales for 28 years, Labour is set to be pushed into third place — and for the first time we could see Wales led by a non-Labour first minister.

“Plaid Cymru are the clear beneficiaries of a country ready for change and could be on course to lead a Welsh government for the first time.

“The other story of this election is Reform’s breakthrough. They have firmly displaced the Conservatives as the party of the Welsh right.”
