The hon. Gentleman has pre-empted me. I will come on to those precise points, so bear with me.
In a democracy, people have the right to change their minds, but we cannot provide procedures for them to do that every day, every week, every month or even every year. There are, however, circumstances in which it is legitimate to revisit the question. I would set three tests. The first is: has the information on which the original decision was made changed significantly? In this case, it has. Far more information is available now than was available three years ago, and some of the promises that were made appear, even to those who proposed them, not to be possible to deliver. Secondly, have people changed their mind on the subject by an extent significant enough to suggest that the result would be different were the question asked again? Thirdly, has the legislature—the Parliament—that is charged with the responsibility of executing the decision of a referendum proved unwilling or unable to do so? I contend that the first two of those tests have been met and the third will be met tomorrow night, when the Government’s proposal crashes and burns.
