Its no surprise that the SNP have rejected the Calman Commissions recommendations for more taxation and other powers for the Scottish Parliament as an alternative to independence. Independence was ruled out of the remit. And to be fair, no other party has pledged to implement Calman either, in the depths of recession. However, last night the SNPs Constitution Minister Mike Russell went further than the Heralds story. He was perfectly prepared to incorporate a Calman package in a multi-option referendum, details to be announced on or about St Andrews Day, November 30. Stand by for a UK government White Paper in reply. Mike is the most engaging of politicians but I couldnt follow his answer to my question: what is your threshold for public approval for independence in a multi- option referendum? Nor was he willing to disclose yet what the precise wording of the independence question would be. Because of legal restrictions in the Scotland Act, such a question could only be to mandate the SNP government to begin negotiations with Whitehall. Mike ahowever rejected as undemocratic the Constitution Units judgement that a second referendum to approve the terms could be needed. Meanwhile the latest poll suggests Labour are heading for a comfortable win in the Glasgow north east by election on Thursday and a reduction in the SNP lead for Holyrood. In a pretty volatile situation, 43% register dont know. Taken with the previous You Gov poll, the trend suggests that Alex Salmonds hopes for 20 Westminster seats have taken a blow, that the likelihood of a 2010 referendum is receding and that Labour have a good chance of retaking power in Holyrood in 18 months time.
