The leader of Plaid Cymru is hoping to become Welsh first minister as early as Tuesday after his party won a historic victory in the Senedd elections, soundly beating Labour and holding off Reform UK.

Plaid fell short of winning a majority in the Welsh parliament but Rhun ap Iorwerth said on Sunday he hoped other parties would work with him and told UK Labour not to punish Wales over the result.

‘Critical debate’ about party’s identity and direction looms if it loses control of Senedd next month after 27 years in power

Welsh Labour is the democratic world’s most successful election-winning machine, coming first in Wales in every general election since 1922 and every devolved election since 1999. Come next month’s Senedd election, however, this history-making run is expected to end.

Labour’s collapse has left a vacuum, and former Labour voters are going to opposite ends of the political spectrum. Plaid Cymru and Nigel Farage’s Reform UK are neck and neck in the latest poll, although coalition maths make it highly unlikely Reform would be able to form a government.
