Story summary
On September 14, 2026, the leaders of Scotland's SNP, Wales' Plaid Cymru, and Northern Ireland's Sinn Féin met in Cardiff to sign a memorandum of understanding pushing for referendums on independence from the UK. The meeting included SNP leader John Swinney, Plaid Cymru leader Rhun ap Iorwerth, and Sinn Féin vice president Michelle O’Neill. They declared their right to self-determination, asserting that no Westminster government has the authority to block democracy or undermine their peoples' ability to decide their own futures. The agreement marks a significant moment as it's the first time all three nations have first ministers committed to independence from the UK simultaneously. Despite this stance, Rhun ap Iorwerth did not provide a timeline for a referendum in Wales, while John Swinney and Michelle O'Neill called explicitly for referendums in their respective countries. The meeting highlights growing dissatisfaction with the current constitutional arrangement within the UK, particularly following Prime Minister Andy Burnham's earlier suggestion that another Scottish independence vote could be allowed if there was a "clear consensus" in Scotland, which he later clarified to mean not being held back by the UK system. Critics argue this move is divisive and threatens the unity of the United Kingdom.
