Picture released 18 November 2007 shows Britain's Queen Elizabeth II and her husband, the Duke of Edinburgh walk at Broadlands, Hampshire, earlier in the year. Queen Elizabeth II and Prince Philip are to mark their diamond wedding anniversary in reserved style 19 November 2007 before jetting off to Malta to revive golden memories of their newlywed youth. Queen Elizabeth, 81, is known to cherish the time they spent on the Mediterranean island as a young couple, out of Britain and out of the spotlight in the years before she inherited the throne aged 25 in 1952.
