European Union Bill

I am interested that the hon. Gentleman would not agree to a referendum on Turkey, which is a simple proposition for the British public. Would he have agreed with a referendum on, for example, the establishment of the European Systemic Risk Board or the European Securities and Markets Authority, or on authorities affecting occupational pensions and so on? Those changes have created pervasive powers across Europe over our financial systems, so they are important. Is he saying that he would have referendums on those authorities, which are quite complicated to understand, but not on whether Turkey is in or out?
