In April 2024, Humza Yousaf, first minister of Scotland and leader of the Scottish National Party (SNP), faced a confidence challenge following his termination of the Bute House Agreement between the SNP and the Scottish Greens, which meant that Patrick Harvie and Lorna Slater, co-leaders of the Greens and their only government ministers, were removed from government. This was following changes to landmark climate policy by Cabinet Secretary for Wellbeing Economy, Net Zero and Energy Màiri McAllan, after which a planned Greens vote on the continuation of the agreement was announced. Facing a motion of confidence in him Yousaf announced his intention to resign as first minister and party leader on 29 April.

The Bute House Agreement, officially the Cooperation Agreement between the Scottish Government and the Scottish Green Party Parliamentary Group was a power-sharing agreement between the Scottish National Party (SNP) government and the Scottish Greens which was agreed in August 2021 to support the Third Sturgeon government and then was reaffirmed to support the First Yousaf government.
