Boris Zipped

London Mayor Bouncy Boris tried out a new zip wire at an Olympic live screen event in Victoria Park today. He lost momentum and was left dangling on the wire for 5 to 10 minutes. Undaunted, plucky Boris entertained the crowd by waving his Union Jacks and spouting jingoist stuff about Team GB and gold medals. Laura Mullane caught some of Bouncy's dangling moments on Boris cam. PM David Cameron said: "If any other politician got stuck on a zip wire it would be disastrous. With Boris it's a triumph...." Aye, there's the rub, David. CLICK to see footage of Boris dangling.
