PA Media The Scottish Green Party will announce the winners of its leadership election on Friday. The party will elect two co-leaders from four nominees; Dominic Ashmole, Ross Greer, Gillian Mackay and Lorna Slater. The party said no candidates were running as a slate, so any combination of two out of the four could be elected. Typically, a male and female co-convener is elected. The results will be announced at 10:00 during an event at the Scottish Poetry Library.
