Adam Boulton and guests focus on the complicated row at the heart of politics in Scotland where - in the past week - Alex Salmond and Nicola Sturgeon have given lengthy evidence to a Holyrood inquiry investigating the handling of harassment complaints against Mr Salmond.What's been happening in the Scottish Parliament and where does it leave the First Minister, the SNP and the future of the independence movement?Joining Adam this week are the editor and publisher of Reaction Iain Martin, journalist and broadcaster Lesley Riddoch and Sky's Scotland correspondent James Matthews.
