Nationalist leaders from Scotland, Wales, and Northern Ireland are scheduled to convene in Cardiff for a meeting described by critics as a "separatist summit." The gathering, set to take place tomorrow, will focus on strategies for pursuing independence movements within their respective nations.

The leaders attending are John Swinney of the Scottish National Party (SNP), Michelle O'Neill of Sinn Fein in Northern Ireland, and Rhun ap Iorwerth of Plaid Cymru in Wales. This meeting marks a historic occasion as all three countries are led by separatist-minded first ministers for the first time in modern history.

Plaid Cymru recently entered the Welsh government in May following an election that ended over two decades of Welsh Labour's rule. This political shift sets the stage for discussions on potential avenues for greater autonomy or full separation from the United Kingdom.

Mr. ap Iorwerth indicated in a BBC interview that the summit would explore a "pursuit of a different attitude" from the UK government. This could encompass discussions on the constitutional question and demands for increased financial resources from Westminster. He also stated that the leaders would discuss common ground and areas of divergence, citing cooperation on issues like child poverty in Scotland and renewable energy economics in Northern Ireland as examples of potential collaboration.

Discussions are also expected to touch upon the transfer of powers, with Mr. ap Iorwerth expressing interest in pursuing control over natural resources, policing, and justice. Policing is a devolved matter in Scotland and Northern Ireland but remains under Westminster's purview in Wales.

The summit follows recent comments by Andy Burnham, who stated that a new referendum in Scotland would require a "majority of public support." Elections expert Sir John Curtice later suggested that polling data could be interpreted to support the SNP's argument for a new vote, prompting a stronger stance from the Prime Minister against holding one. The Conservative shadow secretary of state for Scotland, Harriet Cross, criticized the planned meeting, labeling it "another blatant plot to break up the UK" and a distraction from domestic issues by the SNP.
