Camilla's Clanger

The Duchess of Cornwall's bid to turn on the Christmas lights at Britain's oldest shopping arcade failed when a tassel came off in her hand.
The Duchess, 62, was invited to illuminate London’s exclusive Burlington Arcade, which opened in 1819. After a countdown from shoppers, she went to turn on the lights by pulling a rope with a large gold tassel, and the tassel came off in her hand report Will and Guy.
The blunder was met with howls of laughter from the crowd of guests, while the Duchess looked around sheepishly with a broad grin on her face. The row of 19 geometric light sculptures which lined the arcade's roof eventually lit up after a short delay to cheers from the crowd.
Other Camilla Clangers
The embarrassment follows several other incidents in which the Duchess has been left red-faced at opening ceremonies:
a) In 2007, the Duchess failed to smash the bottle of champagne at the naming of the Queen Victoria cruise liner.
b) Early in 2009 she was also reduced to laughter when she broke a plaque at an unveiling ceremony for a homeless charity in Plymouth.
