The mother of Princess Diana claims in a new book that the Royal family refused to let her hug her daughter’s body a final time after she was killed in a Paris car crash.Frances Shand Kydd also says in the biography that Buckingham Palace did not allow her to travel to Paris to accompany Diana’s body back to Britain. For kydd, the episode brought back painful memories of the birth of Diana’s brother John, who died hours after he was delivered. Kydd says doctors kept her from seeing the deformed baby boy. ‘‘I did not see or touch or hold either of them when they were dead,’’ Kydd says. ‘‘I do ache about it.’’In Frances: The Remarkable Story Of Princess Diana’s Mother, Kydd tells authors Max Riddington and Gavan Naden that she was proud of her family on the day of Diana’s funeral. ‘‘Proud of her, proud of my other daughters who were rock-steady in their readings at the service, and proud of my son (Charles), who gave the ultimate tribute of brotherly love,’’ she says.
