Home Secretaries who go on about how "tough" they are, and that is most of them, always turn out to have been rubbish when you check the facts. Michael Howard arranged Royal Pardons for his violent, drug-dealing cousins in Swansea.
And you don't have to imagine Boris Johnson as Foreign Secretary. Astonishingly, such is in fact the case.
Not only that, but he is already popping up on the airwaves to invite us to imagine him as Prime Minister.
