Plaid Cymru's First 100 Days in Welsh Government: What's Been Done and What Comes Next
Plaid Cymru has marked its first 100 days in government in Wales, with ministers saying they have laid the foundations to improve public services and made "tangible" progress BBC News. The milestone, reviewed by BBC Wales on 26 August, comes just under three months after Rhun ap Iorwerth became First Minister following Plaid's victory in the Senedd election on 7 May BBC News. The Senedd is Wales's devolved parliament, equivalent in role to the Scottish Parliament at Holyrood.
The party's first-100-days agenda was set out publicly well before polling day. Plaid unveiled the plan at its spring conference in March, while Labour staged a rival campaign launch on the same day BBC News. The document, published on the Party of Wales website, detailed pledges across several fronts: improving relations with Westminster, expanding childcare provision, and reforms to education ITV News Wales. The Welsh Government subsequently published its own "First 100 Days Plan" covering May to August 2026 on the gov.wales site Welsh Government.
At the core of the programme is a joint policy agreement spanning 46 policy areas Plaid Cymru. These range from the delivery of free school meals to all primary school pupils through to broader commitments on public service reform. The government's spending plans, totalling £294 million, include £40 million earmarked for school repairs and upgrades BBC News.
One aspect of the programme that invites closer attention is the commitment to improve Westminster relations. Plaid, as a Welsh nationalist party entering government for the first time, faces a structural tension: it must administer the devolved powers Wales already has while also campaigning to expand those powers. How ministers calibrate that dual role — engaging constructively with Whitehall departments while maintaining a distinct political identity — will be a measure of the government's operational maturity.
The childcare and education commitments, while domestic in scope, carry fiscal implications. The £294 million spending envelope sits within the Welsh Government's existing block grant allocation from the Treasury. In practice, this means the money Wales receives is largely determined by the Barnett formula, a mechanism that adjusts the devolved nations' budgets in line with spending changes in England. New commitments therefore require either additional Barnett consequentials (the knock-on funding devolved administrations receive when Westminster spends more in England on comparable services), reprioritisation from other budgets, or both. The £40 million for school repairs addresses a maintenance backlog that the Welsh Government's own estate surveys have long flagged, but the scale of need is understood to exceed the allocated sum.
The 46-policy-area programme is notably broad for a first-100-days framework. In devolved governance, such plans typically prioritise a narrow set of deliverable commitments to establish credibility. The breadth of Plaid's agenda, covering everything from free school meals to Westminster engagement, raises questions about sequencing and capacity within the civil service to deliver across all fronts simultaneously. The party's self-assessment of "tangible" progress will inevitably be tested against the harder benchmarks of budget execution and legislative timetables in the autumn.
BBC Wales's review, published on 26 August, focused on the related topics of Wales, Plaid Cymru, Rhun ap Iorwerth, and the Welsh Government, scrutinising the gap between the party's March conference pledges and the delivery record to date BBC News Wales. ITV News Wales carried out a parallel assessment on 25 August, examining whether the party has kept the specific promises made in its published action plan ITV News Wales.
All health, education, and local government policies discussed apply to Wales only, as these are devolved competencies exercised by the Senedd. The Senedd has 60 Members of the Senedd (MSs) and was elected on 7 May 2026, returning a Plaid Cymru government for the first time in the institution's history BBC News.
The next test for ap Iorwerth's government will come with the autumn budget round, when spending commitments outlined in the first-100-days plan must be reconciled with the fiscal envelope available under the Barnett formula. The passage of primary legislation through the Senedd on the free school meals commitment and childcare expansion will provide the first concrete measure of the government's parliamentary management and its ability to translate programme commitments into binding statutory obligations.
