The more the SNP decries the Internal Market Bill, the more I warm to it. Initially, I considered it sensible enough but wholly insufficient given the constitutional threat facing the United Kingdom. (Less keen on the law-breaking bit, mind.) But now Mike Russell, SNP constitution minister and professional hysteric, says the Bill will ‘undercut the existing settlement’ by allowing devolved administrations to be ‘overridden by the whim of the UK Secretary of State’ and by permitting ministers to spend ‘in opposition to the Scottish government’ in what he calls ‘an enormous assault on the devolved powers’.
