On the subject of respect for all nations of the United Kingdom, the amendment puts forward the view that a simple majority across the UK would not be enough to have the UK exit the European Union but that we would have to pay attention to the voting in the four constituent nations of the United Kingdom. It is not unusual, in international terms, even in federal and confederal states, for there to be a so-called double majority—in this case, a quad lock between Scotland, England, Northern Ireland and Wales. In America, 14 states can block a constitutional amendment, even if they could comprise only 5% of the population. My hon. Friend the Member for Ochil and South Perthshire (Ms Ahmed-Sheikh) will go through some of the other international examples where even in federal and confederal states there is a double lock or a blocking minority with regard to the constitution, recognising the component parts of those states.
