European Union (Finance) Bill

I am sure that my hon. Friend appreciates the difficulties inherent in this matter. It is all very well to want to disaggregate the eurozone from the non-euro member states, but the reality is that we are all part of the same European Union. Any attempt to make a change of this kind would involve a fundamental change to our relationship with the EU and would therefore require a treaty change by any reasonable standards. Does he appreciate how serious the position would be if we neither sought nor achieved that objective?
