I've been thinking long and hard about this.
As an English person living on the South Coast, I'd not presume to tell the Scottih people, for whom I have the greatest affection and regard, what they should or shouldn't do. I do though quite understand why they might want to leave the UK, particularly given recent events - I'd quite like to leave myself!
I do wonder though whether tactically the Scottish Nationalists, and the people of Scotland, might not be better off - at least in the short to medium term - pushing for ever greater devolution and increased financial support from Westminster. I think of this as the Quebec option, though I'd be the first to accepts that this might not be a terribly good analogy. Maybe Vlaams/Wallonia would be better.
But, whatever, once increased Scottish devolution is achieved and locked in it would be very difficult for Westminster to claw it back, and it would be an even firmer springboard from which to push for independence at a later date should the Scottish people still want it.
I'm quite happy to be shot down in flames, at least by our Scottish members!
