George Osborne burger: 10 political gaffes Probably the defining moment of the 2010 general election. Gordon Brown meets an old lady - and Labour supporter - who expresses concern about the levels of immigration to Britain. A microphone catches his private reaction: "They should never have put me with that woman. Whose idea was that? ...she was just a bigoted woman. Minutes later, the tape was played to Gordon Brown on the Jeremy Vine show and - another gaffe - Brown didn't realise he was live on TV. Ed Miliband: These strikes are wrong The Labour leader decided to imitate a robot in this interview by ITV news. The result, played in full, is "one of the most unsettling I've seen with any politician, let alone the Leader of the Opposition," said our Blogs Editor Damian Thompson. Boris Johnson's zip wire fail An Olympic fail by the Mayor of London, who became stuck on a zip wire in the summer of 2012 when a publicity stunt went wrong. "Get me a ladder," he squealed, as he dangled for five minutes in obvious discomfort. David Miliband's banana At the 2008 Labour party conference, David Miliband brandished a banana at photographers. It looked weird. Naturally, Tory spin doctors made the most of it: life-size cut outs of the photo appeared at Tory conference that year, and even found their way to the offices of the Telegraph. Neil Kinnock falls into the sea "If you want a real scoop," said Neil Kinnock to the press pack at his party's 1983 conference, "I'll walk out there, on the water." The Labour leader didn't quite pull it off. He was knocked over by a minor tsunami on Brighton beach with his wife, Glenys, and got soaked. Strangely, he was elected leader of the Labour party later that day. John Nott storms out A "here today, gone tomorrow politician." That was the line that pushed John Nott, the Defence Secretary, over the edge. He walked out of the interview with Robin Day. It was October 1982, shortly after the victory in the Falklands, and Nott had just addressed Tory party conference. Twenty years later, Nott wrote in the Telegraph that "it seemed then, and still seems now, to have been an incident of utter triviality. But the BBC, as an entertainment medium, thrives on triviality. Chris Grayling's 'political gimmick' When General Sir Richard Dannatt was appointed as a Tory defence adviser in 2009, you might have expected Chris Grayling, the then Shadow Home Secretary, to welcome the move. Alas, Grayling misunderstood the question: he thought Dannatt had been appointed by Gordon Brown. "I hope this isn't a political gimmick," he said. We've seen too many appointments in this government of external people where it's all been about Gordon Brown's PR. He admitted later the mistake "was a bit embarrassing really." John Redwood Welsh anthem The Secretary of State for Wales didn't know the words of the Welsh National Anthem, Hen Wlad fy Nhadau. So he tried to mime: big mistake. John Gummer: BSE blunder Another burger to finish. In May 1990, at the height of the BSE crisis, John Gummer was photographed trying to force his daughter to eat a beefburger at a boat show in Ipswich. It was "absolutely delicious," said the Tory agriculture minister, but four-year-old Cordelia didn't seem so keen. "This was parental irresponsibility at its highest level," said a letter-writer to The Sun.
