Conservative Conference sketch: David Cameron, cleared for take-off On whether he'd implement the recommendations of Lord Leveson: "We've got to wait." On a yes/no referendum on Britain's EU membership: "I don't want to have to say yes to the status quo, but I also don't think it would be right to leave right now." On taxing the richest: "We're going to take further action." Such as? I'm not going to announce the measures on your programme, I know that's sad for you... In short, a mixture of "Let's wait and see" and "You'll have to wait and see." Marr inevitably brought up the subject of Boris Johnson. On cue, Mr Cameron donned his special Answering Questions About Boris face, which consists of a tolerant, parental smile that seems to say, "Ah yes, dear old Boris, what a card, I do love his antics, ha ha, I was rather hoping you'd bring him up." Would the Mayor of London, asked Marr, be Prime Minister one day? For some reason Mr Cameron wasn't absolutely clear about that, but he did at least say this: "I've said to Boris, "Once you've done your job as London Mayor, don't think that your job in politics is over." You can readily imagine how Mr Johnson, diffident and unambitious chap that he is, received this generous endorsement. I say, Dave old bean, do you really think so? That's awfully decent of you. I must admit I simply hadn't given my future a thought. What sort of job you reckon might suit me? I make a frightfully good cup of tea, and I'm a positive whiz with the old Hoover. As long as you don't think I'd be stepping on your toes... Of course, as he'd said earlier in the interview, Mr Cameron is passionate about "unlocking the aspirations of people who want to get on," so we can be sure he'll be delighted to support Mr Johnson in whatever career goal he has in mind.
