Here's some irony for you: the Tories, who are the people the "independence movement" is complaining about, would gleefully sign off on Scottish independence because it would give them complete and permanent dominance over the rest of the UK - without the Scottish MPs there is no possibility of any other party controlling the UK government. (Post-independence Scotland would likely have a very unhappy experience negotiating with a permanent Tory government)

LDs will back the outcome of the referendum whatever happens. Labour are the only party that might attempt to ignore the referendum because Scottish independence will end their existence.
