This week is has come to light that Prince Charles was secretly questioned by police in 2005 over claims he had plotted to kill his ex-wife Princess Diana. She was killed in a car crash in 1997.
Police Had To ‘Follow The Evidence’ And Interview Charles
John Stevens, the former head of Scotland Yard, told DailyMail  on Monday that he had to “follow the evidence” and question Charles.
A note was found in which Diana chillingly claimed that he was planning a car accident.
She had written the note two months after her 1996 divorce from Prince Charles.
In the note, Diana predicted that she would be killed due to “brake failure and serious head injury” so Charles could marry his sons’ former nanny Tiggy Legge-Bourke.
“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. Camilla is nothing but a decoy so we are being used by the man in every sense of the word.”
Diana was wrong in that last assertion since Charles did indeed go on to marry Camilla Parker Bowles. However, she did indeed die as a result of a head injury in a car crash.
Police Speak To Charles
Police reportedly interviewed Charles at St. James’s Palace two years after the note was made public.
“Yes, allegations had been made about the Prince of Wales and other royals but we had to find or examine the [existing] evidence before we approached him with formal questions,” Stevens said. “We found no other evidence to support the scenario suggested in Diana’s note.”
“We were left with the note, which in itself was not enough to make Charles a formal suspect,” he added. “If he chose to assist [Operation] Paget, he would be doing so voluntarily as a potential witness. We would not be interviewing him under caution.”
Operation Paget was the police commission established in 2004 to look into the various conspiracy theories surrounding Diana’s death.
Charles agreed to be interviewed, and he was asked by Stevens why he thought Diana wrote it.
Charles Discusses Diana’s Note
“I did not know anything about [the note] until it was published in the media,” Charles replied, adding that prior to it being made public, he “did not know it existed.”
“Do you know why the princess had these feelings, sir?” Stevens asked, to which Charles replied, “No I didn’t,”
In the end, Stevens left the interview satisfied that Charles had nothing to do with Diana’s death.
“At the end of the day he was incredibly cooperative because he had nothing to hide,” he said.
Diana was killed in August of 1997 while being chased by paparazzi in Paris, France. In 2008 an inquest into her death ended with a jury ruling that Princess Diana and her boyfriend were unlawfully killed because their driver and pursuing paparazzi were reckless.
However, there are still those who believe Prince Charles had a hand in her death:
I feel like Prince Charles , put a hit on Princess Diana 🤷🏾♀️

This may lose me followers but I 100% believe that Princess Diana would still be here today had it not been for Prince Charles. That car crash was no accident but then again that's just my opinion!
