First Ministers of Wales, Scotland, Northern Ireland Meet in Cardiff

A meeting between the leaders of Plaid Cymru, the Scottish National Party (SNP) and Sinn Féin is scheduled for 15 September 2026 in Cardiff, where the parties will explore ways to cooperate more closely. The discussion will be led by Plaid Cymru’s Adam Price, SNP’s Humza Yousaf, and Sinn Féin’s Michelle O’Neill. The three parties have expressed a desire to coordinate on policy initiatives that affect the devolved administrations and to align their strategies ahead of the next UK general election.

The talks will focus on shared policy priorities such as regional economic development, climate change, and public services, as well as on potential joint campaigning efforts in the upcoming election cycle. The leaders will also review mechanisms for coordinating legislative agendas across the devolved parliaments and for presenting a united front on issues that transcend national borders, including the UK's relationship with the European Union and the future of devolution.

If the parties reach an agreement, the collaboration could enhance their collective influence in Westminster and the devolved legislatures, allowing them to pursue a more unified approach to national and regional governance. The outcome of the meeting is expected to shape the political landscape in the lead‑up to the next election.
