Plaid Cymru's 2024 manifesto held Welsh independence as a long term commitment. The party won power in Wales by deferring it. On 7 May 2026 Plaid won 43 of 96 Senedd seats on 35.4 per cent, Labour collapsed to nine seats and lost government for the first time since devolution began in 1999, and Rhun ap Iorwerth was elected First Minister on 12 May with Green support. The party that campaigned on independence removed the central constitutional ask from the campaign and won the largest electoral breakthrough of any Welsh nationalist party in history. The gap is between a manifesto built on long term constitutional ambition and a government built on near term devolved delivery.
The deferral was planned. In May 2025, twelve months before the Senedd election, ap Iorwerth stated there would be no plan for an independence referendum in the first term and no referendum talk before 2030. Plaid won by not talking about independence. The party that has long defined itself through constitutional ambition governed Wales without it.
On fair funding the manifesto demanded recovery of the £4 billion HS2 Barnett consequential Wales had been denied. The ask now sits with the Plaid Welsh Government negotiating directly with the Labour UK Government rather than with Plaid campaigning from outside. On the Crown Estate the manifesto demanded devolution on the Scottish model with offshore wind revenues retained for Welsh investment. Plaid will now negotiate it rather than campaign for it. Plaid's leverage has changed from outsider pressure to insider negotiation.
Plaid inherits a National Health Service with the longest waiting times in Britain. The party won by criticizing Labour Welsh Government delivery. Now Plaid owns the record. The defining campaign criticism is now the governing responsibility.
The manifesto's central welfare demand was scrapping the two child benefit cap. Labour scrapped it at the November 2025 Budget. The headline welfare ask has been delivered by the UK Government, not by Plaid.
This is not a party that broke its manifesto. Plaid Cymru did what the SNP cannot currently do: won an electoral mandate that gives the party executive power in its own country. The price was deferral of the constitutional commitment that defined the party for generations. The party that campaigned for independence is now governing without it. Whether the deferral was tactical and reversible or whether the conditions that produced May 2026 require keeping independence permanently parked remains unknown. What ap Iorwerth has set is a 2030 deadline for the answer. Whether Plaid returns to independence before 2030 will test whether the party believes in it or whether independence is now over.
Economy & Tax
Plaid Cymru's 2024 manifesto demanded a fair funding settlement for Wales based on need rather than the existing Barnett formula, devolution of the Crown Estate to Wales on the Scottish model with offshore wind revenues retained in country, and recovery of the £4 billion HS2 Barnett consequential Wales had been denied under the classification of HS2 as an England and Wales project. Windfall tax expansion was framed as central to funding the Welsh green transition.
As of 12 May 2026 Plaid is the party of Welsh Government rather than Welsh opposition. The Crown Estate ask, HS2 Barnett consequential and fair funding demands now sit with the new Plaid Welsh administration negotiating directly with the Labour UK Government rather than with Plaid campaigning from outside.
NHS & Health
NHS Wales is devolved. The manifesto criticised long Welsh waiting times under successive Labour Welsh Governments and committed to an investment package focused on workforce, primary care expansion, and integration of health and social care. The Westminster ask was fair funding and the pass through of NHS England consequentials.
The Plaid Welsh Government inherits NHS Wales waiting times that are among the worst in Britain. The criticisms of Labour delivery in the 2024 manifesto are now the operational record the Plaid administration is responsible for, within weeks of taking office on 12 May 2026.
Immigration & Asylum
The manifesto opposed the Rwanda removals scheme, supported asylum seeker right to work, criticised the hostile environment framework, and argued Wales should have a voice in immigration policy reflecting its labour market and demographic needs. Plaid did not set a numerical net migration target.
Education
Education is devolved. The manifesto committed to expanded Welsh language education provision, maintenance of free tuition at Welsh universities, and additional investment in early years and further education. The Westminster ask was funding consequentials and the continuation of UK student finance reciprocity.
Climate & Energy
The manifesto committed to a Welsh net zero target ahead of the UK 2050 deadline, devolution of the Crown Estate to capture offshore wind revenues for Welsh reinvestment, and opposition to new oil and gas exploration in the Celtic Sea. The manifesto framed climate policy as inseparable from economic development and fair funding.
The Plaid Welsh Government will now negotiate the Crown Estate devolution ask directly with the UK Government. The energy policy implementation pathway has moved from a Westminster lobbying argument to a Welsh ministerial agenda.
Housing
The manifesto pledged expanded social housing investment, second home council tax premiums, and Welsh language considerations in planning policy for rural areas. The framing was that rural Welsh communities were being priced out by the second home market and that housing supply should reflect Welsh demographic and language needs.
Welfare & Work
The manifesto pushed for devolution of welfare administration to Wales, an end to the two child benefit cap and the bedroom tax, a real living wage for care workers, and protections for unpaid carers. The position broadly aligned with Plaid's wider devolved competence ambition for Wales.
Labour scrapped the two child benefit cap at the November 2025 Budget. The headline Westminster welfare demand of the 2024 manifesto has been delivered by the UK Government.
Crime & Justice
The manifesto's central ask was full devolution of justice and policing to Wales, a long standing Plaid commitment going back to the Silk and Thomas Commissions. Plaid argued Wales is the only one of the four nations without devolved justice and that this distorts criminal justice delivery for Welsh communities.
Defence & Foreign Policy
The manifesto opposed Trident nuclear weapons replacement, supported the restoration of overseas aid to 0.7 per cent of gross national income, and committed to continued military and financial support for Ukraine. The framing was Welsh participation in foreign policy decisions rather than a Westminster managed agenda.
Europe
The manifesto committed to pushing the UK Government towards closer alignment with the European Union, opposed the cuts to UK EU trade caused by Brexit, and supported eventual UK re-entry to the single market and customs union. Plaid backed Welsh access to the EU Horizon and Erasmus programmes.
Constitution & Devolution
The 2024 manifesto held Welsh independence as the long term constitutional goal and committed to expanded devolution including justice, policing, broadcasting and the Crown Estate as immediate Westminster asks. The manifesto framed Plaid as building the case for independence rather than calling an immediate referendum.
In May 2025 Rhun ap Iorwerth stated there would be no plan for an independence referendum in the first term of a Plaid Welsh Government and no talk of one before 2030. The deferral preceded the May 2026 Senedd election in which Plaid won 43 of 96 seats on 35.4 per cent of the vote and ap Iorwerth was elected First Minister on 12 May with Green support, the first non Labour Welsh Government since devolution began in 1999.
