A gambler is set to win 72,000 if Kate Middleton wears the Queens wedding tiara when she marries Prince William at Westminster Abbey on Friday. Ladbrokes, the bookmaker, has closed its book on the choice of headgear for the service after one customer bet 6,000 on the 180 year-old George III Tiara. The diamond encrusted decoration, also known as the Russian Fringe Tiara, was a favourite with Queen Victoria and Queen Mary and was also worn by Queen Elizabeth, the Queen Mother. Notably, Princess Elizabeth, the current Queen and Prince Williams grandmother, borrowed it from Queen Mary for her own wedding in 1947. She in turn lent it to her daughter, the Princess Royal, when she married Captain Mark Phillips in 1973. Ladbrokes originally installed the Cambridge Lovers Knot Tiara, previously owned by Diana, Princess of Wales, as its favourite when it started taking bets on the royal wedding headgear earlier this month.
