While 10,000 kids smash up Whitehall outside, Cameron was entertaining the Lobby lunch, the first PM to do so in 31 years. It must have been a good speech for devout Dave-hater Kevin Maguire to announce that “Cameron witty, smooth, confident, clear and direct in answering questions at today’s press gallery lunch. Impressive”.

Guido could hear the laughter from the cellar. Rory Bremner, warming up, declared “Cameron and Clegg have no mandate (for tuition fees) the only one with a man date is Hague”. However it was Dave’s crack about Simon Burns really tickled him. Apparently once when Bercow told Burn “I’m not happy” the Tory Health Minister quipped “Well, which one are you then?”

UPDATE: Paul Waugh has more of the jokes, but comedy aside DC gave the clearest hint yet he wants David Laws back in the Cabinet “soon”. You can bet on just how soon over at Smarkets where prices on Laws to return have jumped…
