The princess was driving to an undisclosed location in London when her BMW was in an accident involving a bus and coach at Hyde Park Corner, a few hundred metres from Buckingham Palace. It is believed no-one was injured in the accident on Monday afternoon, but it is thought Beatrice needed a replacement car. All those involved exchanged details and the police were not involved in the aftermath. A Scotland Yard spokesman said no police action was necessary. Buckingham Palace declined to comment.
