The Story

Leaders of the Scottish National Party, Plaid Cymru, and Sinn Féin signed a memorandum of understanding in Cardiff on September 14, 2026, asserting their nations' right to self-determination and calling on the UK government to prepare for constitutional change.

Scottish First Minister John Swinney stated the meeting represents a pivotal moment in the constitutional journey of the UK and suggested Prime Minister Andy Burnham would be the last UK prime minister. The agreement, signed by Swinney, Welsh First Minister Rhun ap Iorwerth, Northern Ireland First Minister Michelle O'Neill, and Sinn Féin President Mary Lou McDonald, declares that "Our nations have the right to self-determination. No Westminster government has the right to block democracy or undermine the principle that our people will decide their own future."

The parties met in their capacities as party leaders, not as government officials. The SNP and Plaid Cymru advocate for independence for Scotland and Wales respectively, while Sinn Féin campaigns for Irish reunification. The agreement also outlines ambitions for partnership in areas such as the economy, energy, and international cooperation, with a stated belief that the future of their nations belongs in the European Union.

This development follows recent comments from U.S. President Donald Trump supporting a united Ireland. Critics, such as Harriet Cross, the Conservative shadow secretary of state for Scotland, described the summit as a blatant distraction from the real issues facing Scotland. The Labour party accused Plaid Cymru of using its position to break up Britain.

Where they split
