My hon. Friend makes a couple of points about our exposure to Greece and the Bill that is currently going through the House of Lords. As I said, the UK’s exposure to Greece is relatively small, with bank exposure at $4 billion. He will recognise that we have a big interest in ensuring the continued stability of the eurozone. That is why the treaty changes are being made—to put the European support mechanism for eurozone countries on a permanent footing and replace the EFSM, to which we have to contribute thanks to a decision taken by the previous Government, with a mechanism that is funded entirely by the euro area. We do not believe that there is a transfer of sovereignty from this Parliament to Brussels, so there is no need for a referendum on those treaty changes.
