European Union Bill

The hon. Gentleman is making a logical, coherent argument. The Government's position on the Bill, as I was led to believe, was that if there were a significant move towards powers being transferred from the UK to the European Union, there should be a referendum. We have referred to a number of cases when there would be small changes, on which there might be a referendum, but he is talking about a very significant change. Does he not think there should be a referendum on that?
