Story summary

On September 14, 2026, in Cardiff, John Swinney (SNP), Rhun ap Iorwerth (Plaid Cymru), and Michelle O'Neill (Sinn Féin) met as party leaders to sign a memorandum of understanding pushing for referendums on independence from the UK. The agreement asserts their right to self-determination, stating that Westminster has no authority to block democracy. Despite this joint declaration, Wales’ Rhun ap Iorwerth did not provide a timeline for a referendum in his country, while Scotland and Northern Ireland’s leaders called explicitly for referendums. This comes amidst continued opposition from the UK government under Prime Minister Andy Burnham.
