Video: Boris Johnson stuck on Olympic zip wire

Boris Johnson, Mayor of London, was left hanging in mid-air when he got stuck on a zip wire in Victoria Park today.

Johnson, who has something of a reputation for the odd gaffe, went down the zip wire waving two Union Jacks as part of the Olympic celebrations.

However, towards the end the Mayor slowed down before eventually coming to a complete stop above a crowd of bemused and delighted spectators.
