Prince Charles was interviewed by police over an alleged plot to kill Princess Diana, it has been revealed.
Former Metropolitan Police chief John Stevens says he spoke to the Prince of Wales in 2005 as a witness during a three-year investigation into her death in 1997.
According to reports in The Daily Mail, one of the key pieces of evidence in the investigation was a note left by Diana, in which she claimed to fear her death would be caused by 'brake failure and serious head injury'.
The note, which was handed to Diana's butler Paul Burrell, read: "I am sitting here at my desk today in October, longing for someone to hug me and encourage me to keep strong and hold my head high.
"This particular phase in my life is the most dangerous.
"My husband is planning an accident in my car. Brake failure and serious head injury in order to make the path clear for him to marry Tiggy [Legge-Bourke, a nanny with whom Charles was falsely rumoured to be having an affair].
"Camilla is nothing but a decoy so we are being used by the man in every sense of the word."
Lord Stevens reportedly read the note to Charles during a meeting at St James's Palace.
He asked the Prince of Wales: "Why do you think the princess wrote this note, sir?"
Charles replied: "I did not know anything about [the note] until it was published in the media."
Lord Stevens said: "You didn't discuss this note with her, sir?"
The Prince answered: "No, I did not know it existed."
Lord Stevens then asked: "Do you know why the princess had these feelings, sir?"
To which Charles, who was not interviewed as a suspect, replied: "No, I don't."
The letter was first published in full in 2007 as evidence during Diana and Dodi Al-Fayed's inquest.
In 2008, a narrative verdict of unlawful killing as a result of 'grossly negligent driving of the following vehicles and of the Mercedes' was given.
Prince Harry recently revealed that he considered turning to alcohol and drugs to deal with the pain of his mother's death.
Speaking with Oprah Winfrey over the course of three episodes as part of Apple TV's The Me You Can't See, Harry looked back at the impact her passing had on him.
He said: "It was like I was outside of my body and just walking along doing what was expected of me."
Harry struggled to cope in his twenties and early thirties, he explained, adding: "I was willing to drink, I was willing to take drugs, I was willing to try and do the things that made me feel less like I was feeling."
