The SNP leader will face a vote next week following his decision to cut ties with his power-sharing partners in the Green Party.

The Scottish Green Party will join rival MSPs in backing a vote of no confidence in First Minister Humza Yousaf next week, after the SNP expelled its coalition partners from government.

Mr. Yousaf announced his plan to cut ties with the Greens earlier on Thursday, following a bitter row over the SNP’s withdrawal from climate targets.

And soon after, the Scottish Conservatives announced they would submit a vote of no confidence in him, claiming the first minister had “failed” in his role and had “focused on the wrong priorities for Scotland.”

Both Labor and the Liberal Democrats agreed to back the motion, with its success depending on whether Green Party MPs joined the attack to give SNP critics a majority at Holyrood.

Her co-leaders Patrick Harvie and Lorna Slater have confirmed their party will join forces to condemn Yousaf’s leadership, and Green sources told Sky News there was great anger among the ousted party.

How Yousaf’s former rival for the SNP leadership could be crucial in the vote

In the Scottish parliament, the SNP has 63 seats out of 129, two short of an absolute majority.

The Greens have seven, the Conservatives have 31, Labor have 22, the Liberal Democrats have four, there is an Alba MP, Ash Regan – a former SNP leadership rival of Mr Yousaf – and there is also president Alison Johnstone, who He is both representatives of the Republican Party. and the Scottish equivalent of the speaker of the House of Commons.

If Ms Regan, who was previously part of the SNP but defected to Alex Salmond’s Alba Party last October, backs Mr Yousaf, it would mean both parties would have 64 votes, with Ms Johnstone expected to vote for the status quo , so the prime minister would survive.

But if Ms Regan votes against Mr Yousaf, then the opposition parties will have 65 votes to the SNP’s 63, and the prime minister would lose.

If the no-confidence motion is passed, it will still be up to Mr Yousaf to decide how to respond. However, his position will come under increasing pressure if he fails to gain the confidence of the majority in parliament.

However, if a vote of no confidence was passed against the government, the SNP administration would have to resign and appoint a new first minister within 28 days or call an election.

At a press conference, Harvie said: “Humza Yousaf becoming prime minister was based on political cooperation that members of both parties signed in good faith, which Humza Yousaf supported and even two days ago was still supporting.

“Now he has decided to put an end to that. That is his decision and it cannot come without consequences.”

Both he and Slater denied that supporting the no-confidence vote was “revenge”.

Harvie added: “This is about how to achieve the biggest political change for Scotland.

“Humza Yousaf has decided to abandon the vehicle that was generating that progressive change for Scotland. We believe this is a profound mistake.”

The power-sharing deal between the SNP and the Greens was finalized in 2021, after Nicola Sturgeon’s party barely won an absolute majority in the Holyrood elections of the same year.

Both supporters of Scottish independence, the Bute House Agreement between the parties – named after the Prime Minister’s official residence in Edinburgh – brought the Greens into government for the first time anywhere in the UK, and both Mrs Slater like Mr Harvie received ministerial positions.

But signs that the deal was running into difficulties came after the Scottish government scrapped its commitment to reduce emissions by 75% by 2030.

The Greens were also dismayed by the pause of puberty blockers after the historical review of cass of gender services for under-18s in England and Wales.

The party was expected to hold a vote on the future of the deal, but before they had the chance, Yousaf convened his cabinet and announced on Thursday that the deal had “served its purpose.”

The Prime Minister said he hoped to reach a “less formal” deal with his former partners and announced what he called a “new beginning” for the SNP, saying his decision demonstrated “leadership”.

But now that the Greens are willing to join those who oppose the SNP, there is a chance it could instead bring about the end of his premiership.
