Wendy Alexander, Labour Scottish leader, seems to have announced a significant policy shift. She now wants a referendum on independence and may introduce legislation for it. However, the formal position of Labour is unclear and the other parties are somewhat bemused about the potential shift. According to YouGov (buoyed from calling the London elections right) support for independence drops significantly if the option of changes to devolution is included. Also the underlying strength of Unionist support in Scotland means they begin in the stronger position. It allows the Unionist parties to take the initiative, pick the timing and leaves the SNP being the party that does not want to let the people speak.
