Yousaf's leadership is in jeopardy as he faces a confidence vote this week, and Scottish government sources do not expect the Greens to back down following this "spectacular breach of trust." Yousaf unexpectedly ended the Bute House agreement, which secured a progressive, pro-independence majority in the Scottish parliament, causing a political crisis.

Scottish Green co-leader Lorna Slater has announced that her party will support a vote of no confidence against First Minister Humza Yousaf.

This comes after Yousaf broke a trust agreement regarding the Bute House, going against his previous statement that the agreement was valuable.

Yousaf has refused to resign and plans to fight the vote, which is being brought by the Scottish Conservatives and is expected to be debated this week.

Slater described Yousaf's actions as a "spectacular breach of trust." The Scottish Green MSPs, led by Alison Johnstone, have ruled out abstaining in a potential no confidence vote against Scottish First Minister Humza Yousaf.

Johnstone stated that the "Bute House agreement" between the Scottish Greens and the Scottish National Party (SNP) was based on trust and respect, which Yousaf had broken.

The Greens have not indicated how they would vote in a second no confidence vote against the entire Scottish government, which would require the resignation of the first minister and his ministers if successful.
