In 2014 four parties won two or one of Scotland’s six seats, with the SNP topping the poll at 29%. This time SNP support is high enough that they are sure of winning three seats, with the Brexit Party also guaranteed a seat. The remaining two seats are up for grabs between the big two and the other parties (Labour, Conservatives, Liberal Democrats and Greens). With voters able to cast only a single vote for a party list in this PR election, which takes place tomorrow, 23 May, the Democratic Audit team reviews the likely outcomes for the parties, and looks at who the potentially electable candidates are.
