whatever skybird's feelings on the desirability of Britain single-handedly destroying the Eurozone, i think it is politically impossible for Cameron to do that. Hence no referendum.

Note this is not about EU-wide issues, it is about the Eurozone, so does not directly affect Britain.

For Britain to say in this crisis, everything in eurozone decision making must stop while we have a referendum on whether you should be allowed to do this, is inconceivable.

Considering that Osborne has recently been making statements to the effect that a more-integrated eurozone would satisfactorily resolve the crisis from Britain's point of view would make a decision to hold a referendum even more mysterious.

Since time is of the essence at the moment, even if britain said it would hold a referendum, the referendum would never actually happen. The time involved would be too great, and so the eurozone plan would have to choose:

a) alter its plan until britain no longer threatens the referendum
b) disregard Britain's opinion on the matter, and relegate britain to the de facto second tier in euro politics, which is something that Britain is strongly against.
