Britain's €30bn for IMF rescue?

How much should Britain be paying for the IMF eurozone rescue? It's thought the final bill could be as much as €30bn as costs rack up. This is an expense that will have been discussed at the recent EU summit but which David Cameron has given little detail of - so far. The IMF claims that contribution talks are still on-going. But it seems likely that the UK, whatever the outcome, will have to dig deep.
