a threat to public safety. By 10 September, the pile of flowers outside Kensington Gardens was deep in places and the bottom layer had started to compost. The people were quiet, queuing patiently to sign the book and leave their gifts. Fresh flowers, teddy bears, and bottles of champagne were later donated and distributed among the sick, the elderly and children. Cards, personal messages and poems were collected and given to Diana's family. Funeral and burial Early on, it was uncertain if Diana would receive a ceremonial funeral, since she had lost the status of Her Royal Highness following her divorce from Prince Charles in 1996.
