The end of the UK? First Ministers demand independence

The landmark summit, held at the five-star St David’s Hotel overlooking Cardiff Bay, marks the first time in history that all three devolved administrations across the UK are simultaneously led by pro-independence nationalist parties.

Scottish First Minister and SNP leader John Swinney, Welsh First Minister and Plaid Cymru leader Rhun ap Iorwerth, and Northern Ireland First Minister and Sinn Féin vice-president Michelle O’Neill met alongside Sinn Féin President Mary Lou McDonald.

The leaders signed a Memorandum of Understanding calling on the UK Government in Westminster to "prepare, plan, and facilitate constitutional change" across the three nations. The agreement outlines four core pillars of mutual cooperation: economy, energy, European integration, and the democratic right to self-determination.

"For the first time ever, Scotland, Wales, and Northern Ireland are led by pro-independence first ministers," Scottish First Minister John Swinney said. "There could be no clearer sign that the status quo is not sustainable, and that Westminster must prepare for a post-UK future."

The shift follows a dramatic transformation of the UK's political landscape following the May elections, where Plaid Cymru emerged as the dominant force in the Senedd, while Sinn Féin maintained its historic mandate at Stormont alongside the SNP in Holyrood.

The high-stakes summit comes amid escalating constitutional debate in London. UK Prime Minister Andy Burnham recently faced sharp political backlash after suggesting in Parliament that another Scottish independence referendum could be considered if a clear consensus emerged - a statement Downing Street subsequently attempted to clarify by reiterating that referendum demands remain off-limits

Adding an international dimension to the summit, US President Donald Trump publicly voiced support for Irish reunification during a visit to Dublin over the weekend, describing a united Ireland as a "great thing."

Despite the pressure from Cardiff, Prime Minister Burnham rejected the call for fresh independence referendums, maintaining that Westminster's priority remains economic recovery and regional devolution within England rather than constitutional separation.
