Dr Julian Lewis: Does the Prime Minister agree that the question of European bail-outs would be much less likely to arise if different countries with different economies had different currencies? Will he therefore recommend this tried-and-tested model for the eurozone countries?

[The Prime Minister: We have a very strong view in this country that we should keep our own currency, but that does not let us off the need for fiscal discipline, proper monetary policy and keeping inflation under control. It is not a free lunch or a free ride. We have to take tough decisions, but clearly we have to show some respect for the 17 eurozone countries that want to make the euro work. It is no good wishing away what is there. The responsible thing to do is not to stand in their way when they are trying to put out the fire in their own house, but to ensure that they do so in a way that does not threaten our national interests. That is exactly what I have done.]
