To mark the 20th anniversary of her death, well-wishers from around the world have been visiting Kensington Palace to commemorate Diana, Princess of Wales. Banners, cards and flowers have been left at the Palace's Golden Gates, where a blanket of flowers first formed in August 1997. In Paris, Diana is being remembered at the Flame of Liberty statue, which became an impromptu memorial after her car crashed in the nearby Pont de l'Alma tunnel. Here are some of the emotional tributes to the "People's Princess".
