May I sound for the hon. Gentleman two notes of caution? First, he has just said that post-Brexit we are fighting fit. May I remind him that we have not even triggered article 50 yet? We are a member state of the European Union and are likely to remain so for the next two years and two weeks. Secondly, he prays in aid the Red Book, but I cannot see in it—perhaps he can tell me otherwise—any forecasts caveated with a statement that when we do Brexit, the situation may change for the better or for the worse. There are no caveats at all.
