Scottish Green Party Leadership Election 2025

Background

Earlier this year, Patrick Harvie announced that he would not re-contest the position of Scottish Green Party Co-Leader, which he had held jointly with Lorna Slater. A Glasgow MSP since 2003, at the time of this announcement Harvie was by far the longest serving current leader of a Holyrood party. He’d first taken up the then-role of Co-Convener in 2008, an awkward role that combined outward-looking political leadership with inward-focused administrative duties. He held that position right up until constitutional changes in 2019 introduced a more traditional, albeit still diarchic, Co-Leadership. 

By virtue of being the only one of the party’s leadership figures to be an MSP up until 2021, Harvie was consistently the most prominent of the pair at any given time until then. He was in the hot seat through several defining moments. These included most of the SNP’s first tenuous minority government, which nearly fell after the Greens voted against the budget in 2009; the 2014 Independence Referendum, where as the face of the only other Pro-Independence party at Holyrood he got wide exposure; and jointly leading the Greens into government for the first time following the Bute House Agreement in 2021, ill-fated though it was.

Given the length of Harvie’s tenure and recent first-time experience of government, this contest is easily the most consequential leadership election in the Scottish Green Party’s history. Whether folk would admit it to themselves or not, the story of the Scottish Greens following their explosive post-Independence referendum growth has been one of trying to figure out what the point of being a political party is.

Is it a party for hobbyists; nice, well meaning people doing politics to pass their time rather than to win? Is it a party for positionalists; nice, well meaning people for whom politics is about being seen to take a stand and say the right thing? Is it a party for practicalists; nice, well meaning people for whom politics is a means to delivering tangible if imperfect change? What’s the happy medium to be found between these?

Following hot on the heels of the party’s selection process for 2026 MSP candidates, I wondered if this contest would be a real testing ground for that question. In actual fact, all bar one of the party’s sitting MSPs were re-selected at the top of their lists, and with those MSPs making up three of the four candidates, things look set to be a lot more muted than had seemed likely earlier in the summer.

As ever, one thing worth bearing in mind is my own historic association with the Scottish Greens, something I make no secret of. Heavily involved for a total of eight years, I haven’t had any formal involvement since 2021. Nonetheless, social connections don’t disappear overnight, and that’s eight years of insight that few other commentators have.

Voting used the Single Transferrable Vote system. Previous elections have required that at least one of the successful candidates be a woman, but given that was likely to be the case naturally, the winners were effectively the two candidates that were first to exceed a third of the vote during the transfer process.

Candidates

It isn’t just the fact it has two co-leaders that marks the Scottish Greens out as unique. As part of the party’s stated commitment to “radical democracy”, elections for the leadership are held as a matter of routine every two years. It’s also not a requirement for either co-leader to hold elected office, never mind be an MSP. In theory, any member of the Scottish Greens can stand for and be elected as a co-leader.

The routine nature of Green Co-Leader elections means that unlike other parties, the barrier to being nominated as a candidate is much lower. There’s no need for nominations to come from MSPs, councillors, branches, or even a substantial number of members. Candidates require only a proposer and seconder for their nomination.

Dominic Ashmole

Dominic Ashmole is a party activist from the Borders. A candidate, albeit not in a winnable position, on the South regional list, he also contested Dumfriesshire, Clydesdale and Tweeddale in the 2024 UK General Election, and the Tweeddale West ward in the 2022 Scottish Borders Council elections.

Ross Greer

Ross Greer made national headlines in 2016 for being the youngest person ever elected to Holyrood at the age of 21, when he became the first Green MSP for the West of Scotland. Greer has since been engaged in a balancing act. On the one hand, there are capital-L Left policies that have made him something of a bête noire for the Right of Scotland’s political spectrum. On the other, a pragmatic and professionalising approach to the realities of Holyrood governance saw him with a leading role managing the Bute House Agreement with the SNP.

Gillian Mackay

Gillian Mackay was elected as the first ever Green MSP for the Central Scotland region at the 2021 election. She’d previously been one of the Co-Conveners of the Scottish Young Greens, and was one of the party’s candidates at the 2019 European Elections, at which she and I formed the young team on the list. Since her election to Holyrood, Mackay has been the Green spokesperson for the health portfolio, and garnered significant attention for piloting the Abortion Services (Safe Access Zones) Act, aka the Buffer Zones Bill, through Parliament.

Lorna Slater

Lorna Slater has been one of the party’s incumbent Co-Leaders since the role was created in 2019. Previously an engineer working in the renewables sector, she was subsequently elected to the Scottish Parliament in 2021 as one of two Green MSPs for the Lothian Region. The Bute House Agreement signed shortly afterwards saw her enter government as Minister for Green Skills, Circular Economy and Biodiversity until the agreement collapsed.

Results

Gillian Mackay and Ross Greer were elected Co-Leaders of the Scottish Green Party.
