Princess Anne is one of the "unsungheroes" of any success at the London 2012 Olympics, Games chiefs have said.
London 2012 chairman Lord Coe described the Princess Royal's commitment and passion for the cause as "extraordinary" while Olympics minister Hugh Robertson said her impact has been of "inestimable value".
Princess Anne, who is leading the official British delegation which collects the Olympic Flame in Athens today, is president of the British Olympic Association and has been a member of the International Olympic Committee (IOC) since 1988.
