new documentary about the life and legacy of Princess Diana reveals life inside Kensington Palace for young princes William and Harry.
Made by Oxford Film and Television, Diana, Our Mother: Her Life and Legacy is built around contributions from HRH the Duke of Cambridge and HRH Prince Harry, both of whom talk openly about their mother for the first time.
The documentary will be shown on Three later this month to celebrate the life and work of the Princess of Wales, in the 20th year since her death.
A new trailer on Three shows both princes looking through an album of family photographs. Studying a photo of The Princess holding him whilst pregnant with Prince Harry, Prince William says: "Believe it or not, you and I are both in this photograph; you're in the tummy."
The documentary will be the first time the princes have spoken about her as a mother.
"She was very informal and really enjoyed the laughter and the fun.
"She was one of the naughtiest parents."
