Mr Cameron said today at the Conservative Party Conference in Scotland “At the last election, Alex Salmond asked for a mandate for a vote on independence. He won that election. He got his mandate” - this is not the legal position.

The SNP did win a majority on delegated matters in Scotland such as the NHS and education but explicity not on the matter of the Union. Schedule 5 of the Scotland Act 1998 excludes the Union from the range of delegated matters that electors voted on in the Scottish Parliament election in May 2011. General Election decides the Union not referendum.
