LEADERS of the three devolved nations said Westminster’s time was up and that this was a “historic” moment for the United Kingdom as they met in Cardiff today.

Plaid Cymru, the Scottish National Party and Sinn Fein were speaking as they unveiled a Memorandum of Understanding which sets out a commitment to work together.

These include renewable energy, building stronger and fairer economies, strengthening relationships with Europe, and supporting the right of each nation to determine its own future.

Scotland’s First Minister John Swinney, Sinn Fein President Mary Lou McDonald, Norther Ireland FM Michelle O’Neill and Wales FM Rhun ap Iorwerth all said the Westminster government had failed and a new political settlement was needed.

The four leaders predicted that Mr Burnham would be the last Westminster prime minister.

Wales FM Mr ap Iorwerth said: “There is now also a growing recognition that Westminster is not working and that power needs to genuinely be brought closer to people and to communities.

“For people watching across these islands there could be no clearer sign that Westminster’s time is coming to an end.”

Scottish FM Mr Swinney said: “The outcome of the election in Scotland in May was linked to the election of the largest number of pro-independence members of the Scottish parliament in its history.

“There are now first ministers in Scotland, Wales, and Northern Ireland who believe that their countries should decide their own future.”

Ms Lou McDonald said: “I think it is not an exaggeration to say that this meeting today and the signing of this memorandum is historic.

“In our case, we are coming close to the 30th anniversary of the Good Friday agreement, after generations of conflict and hurt and division after centuries of occupation and colonisation.”

US President Donald Trump’s comments at the weekend “in support of Irish unity show that the debate is very much alive,” Northern Ireland FM Ms O’Neill said.

Pro independence campaigners in Yes Cymru welcomed the agreement between the three nations.

A Downing Street spokesperson said the Prime Minister believes strongly in the UK and is focused on easing the cost-of-living crisis for households rather than on “constitutional debates.”

Opposition parties in Wales united in saying the Plaid government should concentrate on fixing the Welsh economy and the NHS.

Welsh Labour leader Ken Skates said: “They clearly want to use power to break up Britain, weaken Wales and spend their time obsessing over more powers for their politicians.”

Plaid and the SNP also signed a separate Cardiff Agreement, with plans for future collaboration between the two governments.

The agreement focuses on working together to tackle child poverty, address cost-of-living pressures, tackle climate change and strengthen language, culture, media and sport.
