The leaders of Sinn Féin, the SNP and Plaid Cymru have said Westminster's time is coming to an end, according to the Irish Independent. The first ministers of Scotland, Wales and Northern Ireland made the joint claim, a position also reported by BBC, The Guardian and RTE.ie.
Scotland's First Minister John Swinney went further, saying that Andy Burnham would be the last Prime Minister of the United Kingdom, RTE.ie reports. The same coverage, carried by BBC and The Guardian, framed the intervention as a shared statement from the leaders of the UK's Celtic nations.
Separately, Sinn Féin warned the British government against blocking a Border poll, according to The Irish Times. That warning sits alongside the leaders' broader argument about Westminster's future role.
The reports, published on Monday, 14 September 2026, draw together the positions of the three parties and their leaders. The Irish Independent, BBC, The Guardian, RTE.ie and The Irish Times all carried the story, with the Irish Independent leading on the "time is coming to an end" line and RTE.ie focusing on Swinney's remark about Burnham.
What to watch next is whether the British government responds to the leaders' claim and how it addresses Sinn Féin's warning over a Border poll.
