The co-leaders of the Scottish Green Party are the leaders of the Scottish Green Party. The incumbents are Ross Greer and Gillian Mackay who were elected in August 2025 as co-leaders. ^{[2] [3] [4]} The co-leaders are responsible for the political leadership of the party, and act as its principle spokespersons. ^[5]

The role was introduced in 2019, following constitutional changes in the party, replacing the co-convenors. ^[6]

Position

The position of co-leaders of the party were created on 1 August 2019, due to changes in the party's constitution. The changes replaced the old co-conveners system with a new co-leader system. An election for this was held, which Lorna Slater and Patrick Harvie won. ^[2]

The voting system used to elect the co-leaders is the Single Transferable Vote. ^[7] The constitution changes also stated that at least one of the leaders has to be a woman. ^[8] Unlike most political parties, Scottish Green co-leaders are only elected for two year terms. ^[9]

For Electoral Commission registration purposes, only one person may legally be named party leader. Initially, this 'leader' was selected from one of the parliamentary group, solely for that administrative purpose. ^[10] However, since the introduction of the co-leaders they have taken it in turn to serve as 'leader' for that purpose.

Notable elections

Most co-leadership elections are only contested by the incumbents. ^{[9] [11]} Some exceptions include:

• In 2015, Maggie Chapman was challenged as co-convenor by activist Zara Kitson in the party's internal elections. ^[12] Kitson was second on the party list for Glasgow in the 2016 Scottish Parliament election and was nominated by former MSP Mark Ruskell and endorsed by MSP and former convenor Alison Johnstone. The election was notable as it was the first time an incumbent co-convenor faced a serious challenge, all to date had been re-elected as the sole nominees.
• In the inaugural 2019 co-leadership election, de facto incumbents Patrick Harvie and Maggie Chapman faced challenges from Lorna Slater, Guy Ingerson and Graham Kerr. ^[13] Harvie and Slater were elected. ^[14]

Co-Leaders in the Scottish Parliament

In 2019 Lorna Slater and Patrick Harvie were elected Co-leaders of the Scottish Greens. As Slater was not an elected official, while Harvie was a long-standing Member of the Scottish Parliament, in the interest of gender-balancing senior female Green MSP Alison Johnstone was appointed Co-leader of the Green Parliamentary Group alongside Harvie. ^[22]

This arrangement ceased upon Slater's election to the Scottish Parliament in 2021.
