CARDIFF — Eighteen months ago, Plaid Cymru was consumed by an internal crisis that many observers believed would relegate it to permanent opposition. On Saturday, with Senedd arithmetic tipping in his favour, party leader Rhun ap Iorwerth stood within striking distance of becoming First Minister of Wales — a transformation that political analysts are calling one of the most remarkable turnarounds in recent devolved politics. The Welsh nationalist party captured 24 seats in Thursday’s Senedd election, a net gain of seven, leaving it as the second-largest bloc in the 80-seat chamber.
The road to this position was neither straight nor smooth. In late 2024 the party was engulfed by a governance scandal that forced out several senior officials and triggered a formal review of its internal structures. Membership fell by an estimated 18 percent over a six-month period, and poll ratings dipped to their lowest point since devolution. It was against that backdrop that ap Iorwerth, already the sitting leader, launched what allies described as a wholesale renovation of the party’s organisation and public positioning.
The renovation centred on a disciplined focus on cost-of-living pressures and public-services investment — themes that resonated with voters in Wales where median household income trails the broader national average by approximately 4,200 pounds per year, according to figures from the Office for Regional Statistics. Plaid campaigners held more than 1,400 doorstep events in the eight weeks before polling day, an intensity of ground campaigning that party officials said exceeded anything in the organisation’s history.
The results rewarded that effort. Plaid’s vote share rose to 28.6 percent, up from 21.9 percent in the previous Senedd cycle, and the party gained seats in six constituencies it had never previously won, including two suburban Cardiff wards long considered Labour heartland. Particularly notable was its performance among voters under 35, where it polled at 39 percent according to an exit survey conducted by the Talisman Research Consortium — a demographic that ap Iorwerth had explicitly targeted with policies on housing affordability and green energy employment.
This result is a mandate for a different kind of Wales, ap Iorwerth told supporters in the early hours of Friday morning, speaking in both Welsh and English to a crowd gathered outside the party’s Cardiff headquarters. We came through a difficult period, we listened to the people of this country, and they have answered. The speech was notable for its measured tone: ap Iorwerth made no triumphalist claims about a coalition deal, instead calling for constructive talks with other parties in a spirit of Welsh national interest.
Coalition arithmetic remains uncertain. With no party holding an outright majority, ap Iorwerth would need to assemble support from at least one other grouping to form a viable government. The Welsh Greens, who secured four seats, and a newly formed centrist alliance holding three seats have both signalled openness to negotiations, which would in theory give ap Iorwerth a working majority of two. Analysts cautioned that such a slim margin would make governing exceptionally difficult, particularly on contentious budget votes.
Political commentator Sian Griffiths, who has covered Welsh politics for more than two decades, said the story of ap Iorwerth’s recovery was as much about personal resilience as structural reform. He refused to resign when many expected him to, he absorbed the criticism, and he rebuilt the party around himself, Griffiths said. That kind of steadiness is unusual in modern politics, where leaders tend to be consumed by the first serious crisis they face. Critics within the party privately acknowledged that his stubbornness, once seen as a liability, had proved to be his greatest political asset.
Formal coalition talks were expected to begin early next week, with a government to be presented to the Senedd within a statutory 21-day window. If negotiations succeed, ap Iorwerth would be the first Plaid Cymru First Minister in the devolved institution’s 27-year history — a prospect that even his closest allies described as unthinkable when the party’s annus horribilis began just eighteen months ago.
One factor that Plaid insiders highlighted as underappreciated in media coverage was the party’s decision to invest heavily in digital and social-media outreach targeting first-time voters. A bespoke campaign on short-form video platforms, produced in-house rather than contracted to an agency, generated more than 4.7 million organic views during the final two weeks of the campaign according to figures the party released Friday morning. That reach, concentrated among 18-to-28-year-olds, translated into measurable turnout increases in university-adjacent constituencies, where Plaid improved on its previous performance by an average of nine percentage points.
