The government might decide that they personally want to leave EU, but I have a passport with nearly 9 years left on it that says European Union.

The next two year however will be a testing time for the liberals as the tories will want to move more to the right to avoid losing support of their traditional nasty xenophobes - oops sorry, voters! If they (liberals) want any smidgen of credibility, they would need to break ranks with the coalition well before then.
