Tony Blair often did it. Barack Obama did it less than three weeks into the job, and last week four of Britain's top bankers did it (though some say they didn't really mean it). Not to be outdone, David Cameron has today claimed he's done it "hundreds of times" – yes, that's right, we're talking about admitting mistakes.
Answering questions from listeners on Radio 5 Live, the Tory leader conceded he had probably made "dozens" of mistakes as Conservative chief. But he said that the Tories' biggest mistake was voting against the government's proposals for trust hospitals.
"It was a mistake to vote against hospital trusts," he said. Cycling to work followed by his chauffeur-driven car was another error Cameron fessed up to. So what were all those other mistakes then, Dave?
