Princes William and Harry prepared to pay tribute to their late mother Princess Diana on Wednesday for the 20th anniversary of her death as wellwishers left candles and flowers outside the gates of her former London residence. The Princes visited the Sunken Garden in the grounds of Kensington Palace, which this year has been transformed into a White Garden, dedicated to their late mother, Britain's Diana, Princess of Wales. / AFP PHOTO / POOL / Kirsty Wigglesworth        (Photo credit should read KIRSTY WIGGLESWORTH/AFP/Getty Images)
