OK. I stand corrected. But if you ever do get to the point of negotiating independence, you won't be dealing with a Conservative government. There's no way Boris or his Tory successors will countenance breaking up the UK (ironically).
On that I bumped into an old friend today: a long-term Scottish Labour member/activist who is pro UK and anti-Brexit, and I asked her what she thought of her party's chance in the forthcoming Holyrood elections (not much, she said), and then we talked of the prospects of Inyref2.
Her view is that the Tories, no matter what they say, might find it in their long-term interests to see Scotland separate from the UK since, given the established support for the SNP here, and as the problems of Brexit and Tory ministerial incompetence become increasingly obvious (and they already are), and if support for Johnson/Tories then erodes and support for Labour increases in England, there is the possibility that at the next GE a resurgent Labour could govern with the support of the SNP (like May arranged with the DUP) and, if so, then the Tories are out - so, according to my friend, the Tories might conclude they'd have a better chance of retaining power if the SNP/Scotland are out of Westminster by the time of the next GE.
Of course, she could be wrong.
