Yes, OK, fair points.
California is welcome to (re-)join Mexico as far as I am concerned. Very strange people over there.
But yes, I get the point about the Labour party being in Scheiße Straße if they go. And also that had this issue been on the table at the last election, there might be a different make-up of Parliament (Westminster).
I still feel though that if they want to do their own thing, there's not much to be done about it. You can't on the one hand say to Argentina that the Falklanders want to remain British and as long as that holds true they will be, whilst not doing the same thing with the Scots (albeit they are voting on NOT being British).
I suppose it is a game of damage limitation in Westminster. I think UK will have the last laugh though, if they go. Be careful what you wish for, you might just get it, as they say.
