The genie is out of the bottle, the toothpaste out of the tube. Pick whichever metaphor you like, but be sure of one thing: it’s a case of “when”, not “if”. The SNP is simply biding its time, waiting for its chance. As soon as Nicola Sturgeon thinks that she stands a decent chance of another crack at independence, she’ll go for it – especially if she can claim a mandate after elections to Holyrood next year. Obviously, it’s not totally up to her. Whoever is in Number Ten at the time will have to consent to it. What choice will they have? Scotland’s right to self-determination has already been established by David Cameron agreeing to hold last year’s referendum. Attempting to deny Scots a second bite at the cherry, or even just trying to delay things, would simply boost the Yes campaign when another vote is eventually held. It will happen – and maybe sooner rather than later.
