Next year will mark 20 years since Princess Diana died tragically in a car crash in Paris.
While there remains questions over her death and the circumstances surrounding her final days, her bodyguard Ken Wharfe says she security team are to blame.
Wharf, who served as Diana's royal protection officer for six years before he resigned in 1993, says her death may have been prevented in an excerpt from his updated memoirs, published by the Daily Mail.
"On behalf of all the professional men and women of the Met's protection squad, let me say that neither [bodyguard Trevor] Rees-Jones nor any of the other bodyguards who attended Diana in the two months preceding her death were from our department," he writes.
"I am still angry beyond words that this team of 'bodyguards' let her come to harm. Our department had the care of her personal safety for some 15 years: Fayed’s crew were in charge of her security for just eight weeks before she died.”
Rees-Jones, a former soldier whom Wharfe says had "none of the necessary training to protect the royal family", was appointed by Fayed to protect the princess during their time in Paris. He was the sole survivor in the crash that also killed Dodi Fayed, and driver Henri Paul.
"I can say with certainty, drawing on decades of police experience, that Diana's death was not murder but a dreadful accident that should have been avoided," Wharfe wrote. "She was not the victim of shadowy figures who regarded her as an embarrassment to the Establishment, but of her boyfriend's erratic behavior and her bodyguard's mistakes."
