It's a day that will remain in our memories forever.
August 31, 1997; the day when Princess Diana passed away following a fatal car crash in Paris.
And now it has been revealed Prince Charles risked his own life walking behind Diana's coffin during the funeral procession, as the future king received death threats in the wake of his ex-wife's tragic death.
In a new Netflix documentary series, titled The Royals, royal biographer and Diana's confidant Andrew Morton admitted that the heir to the British throne received death threats following the death of the Princess of Wales, as everyone blamed him for the accident.
For the public funeral — which took place on September 6, 1997 — there were legitimate fears from royal protection officers that the Prince could be targeted over the late Princess' death.
"During the arrangements for the funeral, there were conversations between Downing Street and the Buckingham Palace and at one of these meetings, they said, 'Well, look if William and Harry decide not to follow the funeral cortege, Prince Charles cannot do that on his own,'" Morton said.
But in the end, Charles walked the funeral procession in his suit and black tie in honour of his ex-wife.
He was joined by Prince Philip, Prince William, Prince Harry, and Princess Diana's brother, Charles, Earl Spencer.
Prince William later revealed that walking behind his late mother's coffin was one of the hardest things he has ever done.
While Prince Harry said that the trauma of the walk in front of millions of people on television was "scarring," and that no child should have been asked to put on such a public display during a time of grief.
