Plaid Cymru is on course to declare victory in the Welsh Senedd elections, a result that would simultaneously end nearly 30 years of Labour dominance in devolved politics in Wales and block the momentum of Nigel Farage’s Reform UK.

By early Friday evening, with 14 of 16 constituencies declared, the centre-left Welsh nationalist party appeared poised to win enough support to lead the nation, replacing Welsh Labour, which had won the largest vote share in every electoral contest in Wales for more than 100 years.
