The political architecture of Wales underwent a seismic shift on Tuesday, as Rhun ap Iorwerth was voted First Minister, marking the definitive end of a century of Labour hegemony. The result, confirmed after a plenary vote in the Senedd, represents not just a change in leadership, but a fundamental realignment of power in a nation that has seen Labour as its primary political engine for 100 years.
Ap Iorwerth, the leader of Plaid Cymru, secured the position with the support of his party’s 43 members and two representatives from the Green party. In a moment of stark contrast to the traditional dominance of the center-left, Welsh Labour and the lone Liberal Democrat in the Siambr—the Senedd’s debating chamber—opted to abstain, effectively clearing the path for the pro-independence leader to take the helm.
The atmosphere in the chamber was electric as the ballot results were announced, punctuated by a standing ovation from Plaid Cymru MSs and the public gallery. For ap Iorwerth, the victory is the culmination of a strategic pivot for Plaid Cymru, which managed to hold off a surging Reform UK and capitalize on a historic collapse of the Labour vote in its ancestral birthplace.
The End of an Era: A Century of Labour Dominance
The scale of the electoral shift is best understood through the numbers. In the newly expanded 96-seat parliament, Plaid Cymru emerged as the largest party, while Labour plummeted to third place with just nine seats. This collapse is a staggering blow to a party that has viewed Wales as its heartland for generations.
The vacancy at the top of Welsh Labour was immediate and visceral; former First Minister Eluned Morgan lost her own seat in the election, triggering an urgent leadership contest within the party. Ken Skates, the MS for Fflint Wrecsam and former cabinet secretary for transport, has stepped in as interim leader to steady a party now facing an existential crisis in the valleys and cities it once owned.
While Plaid Cymru claimed victory, the rise of Reform UK remains the other dominant story of the election. Winning 34 seats, Reform UK had entered the race hoping to be the largest party. Though they fell short of the top spot, their presence creates a volatile atmosphere in the Senedd, with Dan Thomas, the new leader of the opposition, vowing a “robust” challenge to any pro-independence trajectory.
| Party | Seats Won | Status |
|---|---|---|
| Plaid Cymru | 43 | Governing (Minority) |
| Reform UK | 34 | Official Opposition |
| Welsh Labour | 9 | Opposition |
| Conservatives | 7 | Opposition |
| Green Party | 2 | Support |
| Liberal Democrats | 1 | Opposition |
Who is Rhun ap Iorwerth?
At 53, Rhun ap Iorwerth brings a blend of journalistic scrutiny and political discipline to the First Minister’s office. Raised on Ynys Môn (Anglesey), ap Iorwerth spent years as a BBC journalist reporting from both Cardiff and Westminster, a background that has given him a nuanced understanding of the friction between the Welsh Senedd and the UK government.
Entering politics in 2013 and ascending to the leadership of Plaid Cymru in 2023, he has cultivated a persona that is firmly pro-independence but pragmatically focused. In his acceptance speech, he spoke of a “new confidence” and a “broader horizon” for Wales, promising to lead “without prejudice or presumption.”
His approach suggests a departure from the more confrontational styles of previous nationalist leaders. By paying tribute to Eluned Morgan’s “resilience and determination,” ap Iorwerth signaled a desire for a dignified transition of power, even as he prepares to dismantle the policy legacy of the previous administration.
The Challenge of a Minority Government
Despite the celebratory mood, ap Iorwerth faces a grueling legislative road. Under the Senedd’s new electoral system, a majority requires at least 49 seats. With 43, Plaid Cymru is forced to govern as a minority, meaning every major piece of legislation will require negotiation with opposition parties.
The tension is already evident. Dan Thomas of Reform UK reminded the chamber that the Senedd maintains a “pro-union majority,” asserting that the future of Wales lies within the United Kingdom. This creates a paradox for the new First Minister: he leads a nation that has voted for his party, but he governs a chamber where the majority of members oppose his ultimate goal of independence.
To navigate this, ap Iorwerth has signaled a strategy of “mature cooperation.” Rather than engaging in high-profile political rows with Westminster, he intends to press the UK government for expanded powers over specific policy areas, namely policing, and justice. By focusing on tangible administrative gains rather than constitutional warfare, he hopes to build a case for independence through successful governance rather than rhetoric.
A New Order in the Siambr
The restructuring of the Senedd extended beyond the First Minister’s office. In a move that emphasizes the new power dynamics, the Senedd voted for Labour’s deputy leader, Huw Irranca-Davies, to serve as the new llywydd (speaker). Since the speaker role must be held by a member of the opposition, this appointment ensures a level of neutral oversight during a period of expected volatility.
Supporting him is Kerry Ferguson of Plaid Cymru, who was elected deputy presiding officer. This arrangement reflects the complex interdependence of the current parliament, where the governing party must rely on the opposition to maintain the basic functions of the house.
For the citizens of Wales, the shift promises a government that is more representative of the current political mood but potentially more fragile in its execution. The “soul of Wales,” as ap Iorwerth put it, has stirred, but the test will be whether that stirring can be translated into stable, effective policy.
Rhun ap Iorwerth is scheduled to be sworn in by a high court judge on Tuesday afternoon. The immediate focus now shifts to Wednesday, when he is expected to begin appointing his cabinet secretaries and outlining the priorities of his first 100 days in office.
