Nomination period The former leader of the party in the House of Commons, and former party deputy leader,
Angus Robertson, was initially seen as the most likely candidate to succeed Sturgeon by the betting markets. However, on 20 February, he announced that he would not be standing, citing his young family as the reason. The
deputy first minister John Swinney was initially considered another potential candidate. However, he ruled himself out of the contest on 16 February. It was also reported that
Keith Brown and
Màiri McAllan were considering entering the race. On 19 February, Brown ruled himself out of the leadership contest, stating "he could better serve the party in his current post" as depute leader. The same day, McAllan also ruled out standing. With
Kate Forbes's campaign announcement on 20 February, there were expected to be just three candidates: Forbes,
Ash Regan and
Humza Yousaf, the latter two having declared on 18 February. Yousaf was seen as the continuity candidate, supporting the
Gender Recognition Reform (Scotland) Bill, but he did not commit to the idea of using the next general election as a de facto referendum. Regan opposed the Gender Recognition Reform bill but supported a more aggressive version of the de facto referendum plan. Forbes, having been on maternity leave, had been absent from these two debates previously, but later declared her opposition to the Gender Recognition Reform bill. Yousaf and Forbes both supported trying to grow support in Scotland for independence rather than the de facto referendum plan. Once all three candidates had declared, Forbes was considered the most likely winner by bookmakers, followed by Yousaf, with Regan thought to be much less likely to win. After controversy over Forbes's declaration that she would have voted against legalising same-sex marriage, several of her supporters withdrew their endorsements. The social security minister
Ben Macpherson said he had been encouraged by members to stand as a fourth candidate, but chose not to. At
First Minister's Questions on 23 February, Conservative and Labour politicians criticised Yousaf's governance of the NHS.
Kate Forbes The finance secretary
Kate Forbes was on maternity leave when Sturgeon announced her resignation plans. Forbes announced her candidacy on 20 February. She was considered a favourite to win the election from the beginning. She was considered more
centrist than the other candidates and on the political right wing of the SNP, but denied that her leadership would see the party shift to the right. Forbes was the youngest candidate, aged 32 at the time of the election. On independence, Forbes said that she considered Sturgeon's proposal of using a parliamentary election as a de facto referendum to be a way to apply pressure on the UK government to grant permission to hold a formal referendum "rather than it being necessarily a referendum in and of itself". She said she wanted to achieve independence by delivering
economic growth. Members of the SNP expressed concern over Forbes's membership of the
Free Church of Scotland, an
evangelical Calvinist denomination with
socially conservative positions on abortion and LGBT issues. The Church opposes abortion and same-sex marriage, as well as a proposed ban on
conversion therapy. Forbes said she "[makes her] own decisions" on issues "according to [her] faith, not according to the diktat of any church". At a prayer breakfast in 2018, Forbes said that progress should be measured by how society treated the "unborn", a reference to abortion policy. After launching her leadership campaign, she said that she would not have voted to legalise same-sex marriage if she had been in office at the time, but that she would defend it now it was law. Due to these comments, Forbes lost the support of the ministers
Richard Lochhead,
Clare Haughey and
Tom Arthur. She also lost the support of the backbenchers
Gillian Martin MSP and
Drew Hendry MP. Forbes said she had tried "to answer straight questions with straight answers", but that she regretted "enormously the pain or hurt that has been caused" by her comments. On the issue of conversion therapy, Forbes said that any laws should also protect freedom of expression for religious people. On 20 February she said that she would not have supported the Gender Recognition Reform bill in its current form and would have resigned from Sturgeon's cabinet if she had not been on maternity leave during the vote. She does not support challenging the UK government's Section 35 order stopping it, instead seeking to negotiate with the UK government to agree changes to the bill. She said that she disagreed with the principle of
gender self-identification being sufficient for recognition. When asked if
trans women are women, Forbes said that "a trans woman is a biological male who identifies as a woman". One of the co-conveners of the SNP's LGBT+ wing, Erin Lux, reported her to the party over this statement meeting the party's definition for
transphobia. Forbes also said that the
transgender rapist
Isla Bryson, whose case sparked controversy in Scotland, was a man. Members of the Scottish Greens also expressed concern over Forbes' views and suggested that their party might leave their co-operation agreement with the SNP if she became leader. Following her controversial media appearances during the first two days of her campaign, Forbes took 22 February off. The following day, Forbes released a statement saying that she had listened carefully to the criticism and would pledge to uphold and enhance the rights of minorities. On housing, Forbes said that she would set up a new government organisation to build houses in Scotland and allow councils to charge a higher rate of
council tax on unoccupied second homes. She said she would finish the conversion of the A9 and A96 to dual carriageways faster than planned, saying that car ownership was a "necessity" for communities in the Highlands. Deputy Westminster leader of the SNP
Mhairi Black raised concerns that Forbes' social views could cause the SNP to split into multiple parties if she became leader.
Ash Regan The former community safety minister
Ash Regan announced her candidacy on 18 February 2023 and formally launched her campaign on 24 February in
North Queensferry. She said she would abandon the Gender Recognition Reform Bill, which she resigned her ministerial post in protest against. She said she would seek to introduce new laws to ensure all transgender women go to men's prisons and all transgender men go to women's prisons, suggesting "a trans wing on the prison estate". On independence, Regan said that instead of Sturgeon's proposal to use the next Scottish Parliament or House of Commons election as a de facto referendum on Scottish independence, she would begin negotiations with the UK government on independence the next time political parties supporting Scottish independence received more than half of the vote collectively in an election to either parliament. She said she would establish a
constitutional convention with other political parties and organisations that support Scottish independence. She described the SNP as having "dismantled the Yes campaign", saying that she wanted campaign groups to have a greater role in determining the route to Scottish independence. Regan was seen as being close to Salmond's Alba Party: her campaign was run by a Salmond staffer who ran against the SNP as an Alba candidate the year prior, and the only SNP parliamentarian to endorse her is
close to Salmond. During the campaign, Regan insisted she had no interest in joining Alba, and would never join that party; despite this, less than six months after coming last in the contest, she defected to Alba, becoming the first MSP ever to directly defect from one party to another. Regan said she wanted to slow down plans to achieve
net zero carbon emissions by phasing out extraction of oil and natural gas from the
North Sea. She also committed to finishing the
conversion of the
A9 and
A96 to dual carriageways. Regan was considered the candidate that would represent the biggest change from Sturgeon. She said she would not introduce laws that would "[make] things more difficult for businesses" or "interfere with family life". Regan said that
Peter Murrell's positions as CEO of the party and Sturgeon's husband constituted a conflict of interest. In mid-March, Regan said she could give more time to the role if elected leader as she does not have young children, as the other two candidates do.
Humza Yousaf The health secretary
Humza Yousaf also announced his candidacy on 18 February 2023. He said that he wanted to increase support for Scottish independence before focusing on the means of delivering a referendum and committing to challenging the UK government's decision to block the Gender Recognition Reform (Scotland) Bill. He later said that he would not challenge the decision if legal advice said the challenge would not be won. He said that the rapist Isla Bryson was "pretending to be trans for the sake of making their life easier". He said he wanted to hear from members about options for securing another referendum on Scottish independence, but that he wanted to focus on "policy, because if independence becomes the settled will of the Scottish people then those political obstacles will disappear". He said that he is not "wedded" to using the next general election as a de facto referendum on Scottish independence and that one of the issues would be the inability for 16-year-olds and 17-year-olds to vote. He said he strongly supported continuing the co-operation agreement with the Scottish Greens. On 20 February he held a campaign launch in
Clydebank, during which he presented himself as a continuity candidate to follow Sturgeon. He was seen as the candidate most aligned with Sturgeon and the party establishment. Yousaf said that the NHS would have faced the same issues no matter who was health secretary, and highlighted that his negotiations with trade unions had avoided industrial action in Scotland. He said that he would use his approach to pay negotiation in the NHS with every part of the public sector if he became first minister, to try to "make sure we don't have strikes in any industry". As health secretary, Yousaf had proposed a
national care service to move social care from
local government to a central organisation like the NHS. Various groups had criticised his plan, and as a leadership candidate he said he was willing to make compromises. He said that if he won the election, he would consider appointing Forbes to his cabinet. Yousaf committed to continue Sturgeon's
progressive approach, and said that if Forbes won and became first minister he might turn down an offer to serve in her government if she changed the party's social policy positions towards a more conservative stance. In 2014, Yousaf was absent for the final vote on the
Marriage and Civil Partnership (Scotland) Act 2014, citing a ministerial engagement regarding a Scottish prisoner facing capital punishment for blasphemy in Pakistan. He voted for the bill in earlier stages and vocally supported it throughout. The former MSP
Alex Neil, who introduced the act, said that Yousaf had deliberately scheduled the meeting to avoid the vote, with permission from Salmond, "because he was put under pressure by the leaders of the mosque in Glasgow". Yousaf said that he consulted his community and "the Muslim community in particular" about many of his positions, and that there were Muslims who had different views on same-sex marriage. He said he did "not remember any conversation with Alex Salmond about the equal marriage vote". Whilst a practicing Muslim, Yousaf said that he does not "legislate on the basis of [his] faith". Yousaf said that he wanted to provide twenty-two hours a week of universal free childcare to children aged one and two.
Emma Harper MSP sent an email to party members in support of Yousaf using the SNP's email system. This was against party rules, and Harper apologised.
Joanna Cherry MP, who supported Regan, said that the SNP's "party machine" was supporting Yousaf. Yousaf said his first meeting as first minister, if elected, would be with anti-poverty groups. He said he would consider wealth taxes, windfall taxes and part public ownership of renewable energy. He described himself as a
socialist. but this was overturned the following day after criticism. At the first TV debate on 7 March, Forbes said she would seek the "legal powers to hold a referendum" on independence within three months of the new UK general election. During the first televised debate, Forbes criticised Yousaf's record as a minister, saying that he had failed in all his previous roles. She described the Scottish government as "mediocre". Her words were used by Tory leader
Douglas Ross at
First Minister's Questions that week, before his party wrote to Forbes asking to use her quotes in their election material the next week. During hustings at
Glenrothes, Forbes proposed a
sovereign wealth fund to invest in renewable energy while Yousaf said that he would require a 10% state share of ownership in future renewable schemes. A
Survation poll released on 12 March suggested that the percentage of those who intended to vote SNP at the next general election had fallen to its lowest level in five years, while support for independence had dropped to its lowest level since the autumn of 2018. Prominent pollster
John Curtice said the results "strongly suggest" the aggressive attacks by Forbes and Yousaf on each other in the debates had "so far has proven unattractive to voters". During the hustings on
Times Radio on 21 March, Yousaf said that he supported children being taught about gender identity in schools and that there were times that parents should not be informed, citing discussions with a young trans Muslim who told him that his life would have been more difficult if his parents had known he was transitioning. Forbes said that parents should always be involved in decision-making and disputed the language of
sex assignment. On 16 March, the party's national executive committee agreed to publish the figure, which was 72,186 as of 15 February. This was down from 104,000 members in 2021. This then led to the SNP's national executive committee giving Peter Murrell, the party's chief executive (and Nicola Sturgeon's husband), an ultimatum as he was blamed for Foote having been misinformed. This led to Murrell's resignation on 18 March. == Election process ==
