Scotland’s first minister, Humza Yousaf, resigned on Monday, April 29, 2024, in a fresh setback for his Scottish National Party, which has been engulfed in a slow-burning crisis over a funding scandal that erupted after a popular leader, Nicola Sturgeon, stepped down last year.

Mr. Yousaf’s departure had looked increasingly inevitable after he gambled last week by ending a power-sharing deal with the Scottish Green Party.

The two parties had clashed over climate goals and trans rights, but his abrupt decision angered the Greens and left him at the head of a minority government without obvious allies. His opponents then pressed for two motions of no confidence, which are expected to take place later this week.

Having explored his options over several fraught days, Mr. Yousaf, who was Scotland’s first Muslim leader, announced his plan to quit in a speech on Monday at Bute House in Edinburgh, the official residence of the Scottish first minister.
