Sinn Féin & Democratic Unionist Party - 2024 General Election

In the 2024 United Kingdom general election held on 4 July, Sinn Féin emerged as the largest party in Northern Ireland, both in terms of vote share and parliamentary representation. The party maintained its seven seats in Westminster, securing 27.0% of the vote—a 4.2% increase from the previous election.

The Democratic Unionist Party (DUP) experienced significant losses, with their representation dropping from eight to five seats. Their vote share declined by 8.5%, resulting in 22.1% of the total votes.

These results marked a historic shift, as Sinn Féin became the largest Northern Irish party at Westminster for the first time, achieving what has been locally termed the "historic hat trick," following their successes in the 2022 Assembly Election and the 2023 Local Government Election.

Other parties also made gains: the Social Democratic and Labour Party (SDLP) retained their two seats; the Alliance Party maintained one seat; the Ulster Unionist Party (UUP) secured one seat; Traditional Unionist Voice (TUV) gained one seat; and one independent candidate was elected.

This election underscored a significant realignment in Northern Ireland's political landscape, with Sinn Féin's ascension reflecting shifting voter sentiments and the DUP's decline highlighting challenges within unionist politics.
