Re: This goes to show one thing
"Who will be returned in [..] Scotland?"
This is irrelevant. The SNP has 56 of 59 Scottish seats already, but no power over an English (and Welsh) voted Tory majority at Westminster. We could vote for 59 fluorescent macaques and it would have no effect.
Nothing undemocratic about that in the purely technical sense. That's what you (or rather, we) get for remaining a part of a political union with a far larger partner whose political and cultural values have been diverging from ours for a long time.
Still, I'm glad we chose to say "No" to independence, because- as all the scaremongering unionists promised- our place within the EU is safe that way. Isn't it, Mr. Darling?
