The trial of Paul Burrell, former butler to the Princess of Wales, has collapsed after it emerged that he had told Queen Elizabeth that he was keeping some of Diana's possessions.
Mr Burrell was found not guilty of three charges of stealing from the estate of Princess Diana, the Prince of Wales and Prince William.
The Queen had met Mr Burrell some months back but only realised the significance of the discussion last week.
Prince Charles then passed on the information to the police.
