The Bute House Agreement was, despite some policy concessions, popular with the SNP membership, with some 95 per cent voting in favour at the time of the agreement.[10] Some policies were changed to gain the Greens' support,[11] such as their proposal to stop North Sea oil drilling,[12] which some SNP figures, such as Kate Forbes, criticised, alongside their plans to phase out the natural gas industry.[13] The SNP MSP Fergus Ewing, who was later suspended from the SNP group in parliament for a week because of his rebellions,[14] blamed the Greens for the government delaying the duelling of the A9 road, the longest road in Scotland.[15] The controversial Gender Recognition Reform (Scotland) Bill resulted in the United Kingdom government using section 35 of the Scotland Act 1998 for the first time to block the bill.[16] The Green Party's bottle deposit return scheme was delayed in 2023.[17]
The co-operation deal was defended by MSPs from the SNP and the Greens, including Humza Yousaf, who—mere days before ending the deal—stated that he "really valued the deal" and wished "to keep achieving a lot with the Green Party".[18] The Green MSP Ross Greer spoke of the deal's policy achievements, including "record funding for wildlife and nature", "free bus travel for under-22s", and "the most progressive tax system in the UK".[10] Following Sturgeon's resignation and the subsequent leadership election the Greens decided to stay in government.[19]
After the termination of the agreement, the Scottish Conservatives called a vote of no confidence against Yousaf, which the Scottish Greens said they would support.[22][23] Because of the narrow vote margins in the Scottish Parliament, if the vote had taken place, Ash Regan of the Alba Party would have been the sole decider on the vote's result.[24]Alex Salmond, former SNP First Minister and now leader of Alba, called Regan the "most powerful MSP in the Scottish Parliament".[25] Regan, who had left the SNP the year prior, was called "no great loss" by Yousaf at the time of her defection.[26] She sent him her list of demands to secure her support, which included progress on Scottish independence and defending "the rights of women and children".[27]
On 26 April, Yousaf postponed a scheduled speech at the University of Strathclyde on labour strategy in an independent Scotland.[28] The same day he claimed that he had no plan to resign as first minister of Scotland.[29] He claimed the day after that a snap Scottish Parliament election was a possibility.[30] On 28 April, Salmond said that Alba was "prepared to assist" Yousaf in the confidence vote.[31] His demand was a renewed Scottish independence plan.[32] He appeared on Sunday with Laura Kuenssberg and said that the SNP should return to the "people's priorities" of education, jobs and industry.[33] Yousaf reportedly ruled out any electoral pact.[34] It was Salmond who firstly appointed Yousaf to government: in 2012, as minister for Europe and International Development in the Second Salmond government.[35] Chair of the Alba PartyTasmina Ahmed-Sheikh said that an "electoral pact" is not part of negotiations.[36]Scottish Liberal Democrat leader Alex Cole-Hamilton ruled out Yousaf's offer of talks.[37]
Late on 28 April, it was speculated that Yousaf planned to step down the next day, fearing that he could not survive the no confidence vote against him: he did, announcing that he would resign as both leader of the SNP and first minister of Scotland once his successor has been chosen.[38] In his resignation speech Yousaf reasserted that he believed the vote of no confidence could have resulted in his favour, however he choose to resign instead as he was "not willing to trade [his] values and principles, or do deals with whomever, simply for retaining power".[39] The day after, officials at Holyrood announced that Labour's motion of no confidence would be voted on by MSPs the next day, which would have required the entire Scottish government to resign if it were to be passed.[40] The vote went ahead the next day, ending in favour of the continuation of the current Scottish government,[41] with 58 MSPs – from Labour, the Conservatives, the Lib Dems, and Alba – voting for the motion and 70 – from the SNP and the Greens – voting against.[42]
