I am grateful for your comments, Mr Hanson. You are right I have not been present in this particular debate for the whole time, but I have been in many of the debates and this is the first time I have stood up to speak on the issue. I shall not detain the Committee for very long.
Following on from the comments made by my hon. Friend the Member for Stockton South (Dr Williams), of course people in every democracy have the right to change their minds. The correct way to do that is through the same means by which the referendum came about in the first place: a political party should say in its general election manifesto that it wants a referendum, win that election and hold another referendum. The Lib Dems tried that at the most recent election; admittedly, they gained seats, but they lost votes. That is the way to do it, not by calling on the most immediate opinion poll.
Opinion polls change. My hon. Friend the Member for Stockton South and other Members may be interested in a poll taken by Lord Ashcroft the day after the referendum. He surveyed all those people who had voted for Brexit and found that 94% of them had not voted for it on economic grounds, so a lot of the arguments about economics do not apply to the people who voted to leave.
