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.
