John Swinney, Scotland’s Deputy First Minister and a former leader of the SNP, is being forced to hand over key legal advice relating to the botched harassment investigation into Alex Salmond. Swinney caved in on Monday evening when opposition parliamentarians at Holyrood were ready to vote no confidence in him later this week. The Tories led the charge; Labour’s new leader Anas Sarwar signed up; and the key moment came when the Scottish Greens (who usually prop up the SNP) decided that they would vote down Swinney.
