No, it absolutely didnt. The question of a Brexit vote rarely came up as I recall. It was said that perhaps it may be revisited if there was a vote for Brexit. But there was no explicit promise to that effect. Looked at from my perspective, if I dont get a second vote for Brexit, why should Scotland get a second vote for Independence?
The SNP are a one trick pony. They have to bang on and on about independence because, from my understanding, they dont have much else to offer. Education, something that was rightly lauded with pride in Scotland, is on the slide. Policing, and there were many fine Scottish constabularies, were merged, and that is apparently ont he slide. There is a drugs epidemic in Scotland. None of these things are tackled. But still they keep banging on about independence as if it would solve all the problems. Scottish independence will no more solve Scotlands Independence, than will Britains independence of the EU.
All politicians on the make when you get down to it.
