The three leaders have signed a memorandum of understanding at a big meeting in Cardiff - to talk about independence from the United Kingdom
Leaders of Sinn Fein, the SNP, and Plaid Cymru claim the UK's time is "coming to an end", as they call on the British Government to prepare for constitutional change.
The three leaders have signed a memorandum of understanding at a big meeting in Cardiff - to talk about independence from the United Kingdom.
It happens to follow a weekend in which US President Donald Trump backed a united Ireland.
On X, Sinn Féin leader Mary Lou McDonald described today's meeting as "historic".
Also posting to social media was Sinn Féin vice-president Michelle O’Neill, who said today's signing was "an historic moment as the leaders of Sinn Féin, the SNP and Plaid Cymru come together to stand up for the interests of our nations and their right to independence.
"For the first time in history, three nationalist and pro-independence First Ministers now hold office.
"Today is a powerful testament to the enormous change, hope and opportunity of the times we are living through."
