Rhun ap Iorwerth has been confirmed as First Minister of Wales, ending 27 years of Labour leadership of the Welsh Government and making history as the first Plaid Cymru politician to hold the office.
The confirmation came following a vote in the first plenary session of the seventh Senedd, days after Plaid Cymru’s historic election victory last week saw the party win 43 of the 96 seats in the Senedd.
Forty-four Members of the Senedd voted to nominate ap Iorwerth as First Minister — 43 Plaid members plus the support of Wales’ two newly-elected Green MSs, who announced on Sunday they would back the Plaid leader. Reform UK’s Dan Thomas received 34 votes and Conservative leader Darren Millar seven.
Labour’s nine MSs abstained from the vote, as did the sole Liberal Democrat MS Jane Dodds — a decision that effectively settled the arithmetic in the chamber. With no other candidate able to attract more votes than all other candidates combined, ap Iorwerth’s path to the top job was secure.
In his first speech as First Minister, ap Iorwerth told the Senedd: “It is the greatest privilege of my life to be elected first minister in a nation that means so much to me. I’m eager to repay the trust that the people in Wales have placed in us and to achieve the change that people have stated so clearly they wish to see.”
He will lead a minority government, having confirmed last week that he would seek to govern without a formal coalition. With 43 seats, Plaid falls short of the 49 needed for a majority in the 96-seat chamber, meaning ap Iorwerth will need to build support from other parties on a vote-by-vote basis.

The session also confirmed Labour’s Huw Irranca-Davies as the new Presiding Officer — known in Welsh as the Llywydd — with Plaid’s Kerry Ferguson elected as his deputy. The Llywydd chairs Senedd proceedings and is required to remain politically impartial. The previous holder of the role, Plaid Cymru’s Elin Jones, stepped down at this election.
The political landscape ap Iorwerth inherits is dramatically different to any previous Welsh Government. Reform UK came second in the election with 34 seats, Labour were reduced to just nine, the Conservatives won seven, the Greens picked up their first ever two Senedd seats and the Liberal Democrats hold one.
Born in south Wales, ap Iorwerth, 53, grew up on Anglesey and was educated at Ysgol David Hughes before studying politics and Welsh at Cardiff University. A former BBC journalist and married father of three, he entered politics in 2013 when he won a by-election in Ynys Môn.
He took over the leadership of Plaid Cymru in 2023 during a difficult period for the party, after his predecessor Adam Price resigned in the wake of a report finding there was a culture of sexual harassment, bullying and misogyny within the organisation.
Since taking over, he has steadily rebuilt the party’s fortunes — culminating in last week’s historic result. The scale of the victory exceeded most expectations, with Plaid emerging as comfortably the largest party in the Senedd for the first time.
Ap Iorwerth is a supporter of Welsh independence, and has previously said his party would use time in government to make the case for an independent Wales. However he has ruled out holding a referendum during this first term in office.
Welsh Labour’s Mike Hedges has already warned that the new Plaid minority government could face a fresh election as early as next year if it fails to pass its first budget — a significant test for the new administration in its earliest months.
Ken Skates was appointed as interim Welsh Labour leader following the resignation of Eluned Morgan, who lost her seat in the election. Labour now faces a lengthy period of reflection and rebuilding as the official opposition — with just nine seats in a 96-member chamber.
For Wales, the significance of the moment extends beyond party politics. This is the first time since the creation of the Senedd in 1999 that the Welsh Government has not been led by Labour — a shift that marks a fundamental change in the political landscape of the nation.
