I thank the hon. Lady for giving way, and for the points she has made about precedent and about what we do. Does she agree that, even though we have an unwritten constitution in this country, it is constitutional invention that has got us through in times of national emergency? We had a national Government during the two world wars and a full-blown coalition to solve the financial crisis in 2010. Given that the Government do not have a majority and that it is not clear whether there will be a majority for any of the Brexit options, does she agree that what was needed right from the start was that kind of constitutional invention, and that the lack of it has not really helped with the passage of the Government’s withdrawal Bill? We should actually be thanking my right hon. Friend Sir Oliver Letwin for doing this. We would rather not be here, but we are, and invention is what is needed at this time.
