The undefeated world champion light-heavyweight boxer Joe Calzaghe has been arrested by Palace guards, after a ceremony in which he was to receive his CBE from the Queen went dreadfully awry.
Calzaghe from Newbridge, South Wales, was to be recognised for services to sport and voluntary services in Wales, in the Queen's Birthday Honours.
The ceremony, at Buckingham Palace, had just begun when, according to witnesses, the Queen told Calzaghe she thought the decision to award him victory in his previous fight against Bernard Hopkins in April, was "rather dubious".
The Welshman appeared to 'remonstrate' with Her Majesty, before taking one backward step and unleashing a crunching right hand to Her temple, knocking Her sprawling to the marble floor.
Beefeaters rushed to Her aid, and the boxer was led away vowing to "finish her off" when the two next met.
Calzaghe, who was the BBC Sports Personality of 2007, and was awarded the MBE in 2003, said later:
"I didn't want another award anyway. It's not like it's a Championship belt or anything. She can keep it!"
