Marcus Brigstocke offers David Cameron some sleeping tips

A final word (probably) on the memorable exchange between David Cameron and Matt Baker on BBC1's The One Show on Tuesday, in which the former Blue Peter man asked the prime minister: "How on earth do you sleep at night?". Marcus Brigstocke, a guest on Wednesday night's edition of the programme, took up the running. "I saw that, you had a good shot at him in the end and I liked it," he told Baker at the beginning of the show . "You can ask me how I sleep at night if you like. It's easy – I'm not closing libraries."
