Princess Diana "deserves a place in history", according to her brother Earl Spencer.
The popular royal tragically passed away in 1997 aged 36 after she was involved in a fatal car crash in Paris, France, and her brother has now said that 20 years after her passing, the beauty deserves to be honoured as a "special person", even by those who are too young to remember her.
Speaking in a clip released ahead of an American documentary 'The Story of Diana' - which is set to air on ABC in two parts in August - Earl Spencer said: "One of the reasons I want to talk now is because I think that after 20 years someone shifts from becoming a contemporary person, to one of history.
"And Diana deserves a place in history. And I think it's important for people under 35 who probably won't remember her at all to remember that this was a special person and not just a beautiful one.
"Obviously 99.9 percent of the people had never seen her, or met her, but they felt something in her that was fascinating and intriguing, and a force for good."
The clip comes after Diana's sons, Prince William and Prince Harry, were joined by William's wife Duchess Catherine and their children, Prince George, three and Princess Charlotte, two, in a service at Althorp House to re-dedicate the grave of their mother on what would have been her 56th birthday on Saturday (01.07.17).
The private service, which their father Prince Charles did not attend as he is in Canada with his wife Duchess Camilla, was conducted by the Archbishop of Canterbury, Justin Welby.
A statement, previously released by Kensington Palace, stated: "The Duke and Duchess of Cambridge and Prince Harry will attend a private service to re-dedicate the grave of Diana, Princess of Wales at Althorp House on Saturday 1 July.
"The service, which will fall on what would have been The Princess's birthday, will be conducted by The Archbishop of Canterbury and attended by her family."
