Hundreds of soldiers in ceremonial dress have marched in London in the annual "Trooping the Colour" parade to mark the official birthday of Queen Elizabeth II. "Trooping the Colour" originated from traditional preparations for battle, when flags were carried or "trooped" down the rank for soldiers to see. From left are Camilla, the Duchess of Cornwall, Prince Charles, Princess Eugenie, Princess Anne, Sophie, the Countess of Wessex, Tim Lawrence, Prince Philip, Prince Harry, Kate, the Duchess of Cambridge and Prince William.
