Revealed: the chap who was interviewed on Radio 4's World at One who the BBC thought was Lib Dem MP Mike Crockart – but wasn't. Over to Hugh Muir and the Guardian's Diary column. Not the best day for Radio 4, as Naughtie and Marr come over all DH Lawrence. The World at One, meanwhile, interviews an imposter. He was supposed to be Crockart, Lib Dem MP for Edinburgh West, discussing tuition fees. But because of an error in a directory of MPs' phone numbers, the Beeb and the London Evening Standard ended up with "Eric", a prankster working on a building site in Manchester. "At first he thought it was one of the lads having a laugh," said a colleague. "He just went with it. I don't think he knows what a tuition fee is." Just wait until he has kids.
