2019 Scottish Green Party co-leadership election
The first Scottish Green Party co-leadership election occurred during the summer of 2019, following a newly adopted constitution by the party. One article of the constitution stated that the positions of co-conveners would be abolished in favour of the newly established positions of co-leaders. It also said that at least one of the co-leaders had to be a woman. Both of the former co-conveners, Maggie Chapman and Patrick Harvie, contested the election, but when the results were announced at the Out of Blue Drill Hall in Edinburgh on the 1st of August 2019, only Patrick Harvie was elected, alongside Lorna Slater. All Scottish Green Party members were eligible to vote.
Other positions
Changes to the party's constitution create a few new positions which are available for election.The eco-socialist Green Futures Group faction did not nominate a candidate for the co-leader position but contested for the other positions. All seven nominations from the faction were successful in their contests.
