Sinn Féin's 2024 Westminster manifesto centred on the all Ireland economic argument: the dual mandate of Northern Ireland inside the UK fiscal framework and partially inside EU single market rules under the Windsor Framework created opportunities that should be maximised. The manifesto pushed for parity of treatment with Great Britain on fiscal transfers and for the Northern Ireland block grant to reflect need.

NHS Northern Ireland is devolved. The manifesto pushed for an all Ireland approach to health planning, framed as the alignment of Northern Irish and Republic services where cross border efficiency made care more accessible. The Westminster ask was pass through of NHS England funding consequentials and the closing of pay parity gaps.

The manifesto opposed the Rwanda removals scheme, opposed the Illegal Migration Act framework, and supported the right of asylum seekers to work three months after arrival. The framing was Northern Ireland's specific labour market and demographic position requiring a more open approach than Westminster policy permits.

Education in Northern Ireland is devolved. The manifesto committed to expanded integrated education provision, maintenance of free university tuition for Northern Irish students, and an Irish language strategy in schools. The Westminster ask was funding consequentials and continued UK student finance reciprocity.

The manifesto pledged Northern Ireland alignment with the UK net zero target while pushing for all Ireland climate cooperation through cross border infrastructure investment, particularly in offshore wind. The position broadly tracked UK climate policy with all Ireland framing as the distinctive Sinn Féin addition.

Housing in Northern Ireland is devolved. The manifesto pushed for expanded social housing investment, Local Housing Allowance uplifts, and an all Ireland framework for cross border worker housing access. The framing was the housing crisis as a structural feature of partition that an all Ireland approach could address.

The manifesto opposed the two child benefit cap, the bedroom tax and the wider Conservative welfare framework, and demanded parity of welfare protection with Great Britain. The Westminster ask was full pass through of UK welfare uprating to Northern Ireland and a real living wage policy.

Criminal justice and policing in Northern Ireland are devolved. The manifesto pushed for an end to the legacy of the Troubles legislation that Sinn Féin argued failed both victims and reconciliation, and for police service reform including community policing expansion.

The manifesto opposed Trident nuclear weapons renewal, opposed Northern Irish military involvement in NATO operations, supported restoration of overseas aid to 0.7 per cent of GNI, and demanded UK Government acceptance of the call for an Irish unity referendum as set out in the Belfast Good Friday Agreement. Sinn Féin has historically opposed UK military engagement abroad.

Sinn Féin's 2024 manifesto supported the operational position created by the Windsor Framework, which keeps Northern Ireland inside parts of the EU single market for goods, and pushed for closer all Ireland economic alignment that would deepen the framework's working. The position was broadly distinct from the DUP and TUV demand for the framework's removal.

The defining 2024 manifesto commitment was that the British and Irish Governments set a date for a referendum on Irish unity by 2030, supported by a citizens' assembly and a joint Oireachtas committee to plan the constitutional change. The manifesto framed Northern Ireland's continued constitutional status as failed partition. The Westminster seven seats won were and remain abstentionist by principle, with Sinn Féin MPs not sitting, speaking or voting in the Commons.
