Prince Charles was probed for Diana's note: 'My Husband Is Planning an Accident'

Prince Charles was investigated on Princess Diana's death in 2005 after almost a decade after the death of Princess of Wales.

The probe was held on the grounds of a letter that was written by Diana a year before her death in 1997.

"My husband is planning 'an accident' in my car, brake failure and serious head injury," so that he could marry Tiggy Legge-Bourke, a nanny for Prince William and Prince Harry wrote Diana.

Prince Charles was interviewed at St. James's Palace as a witness two years into the investigation after the note became public in 2003.

The police asked the royal questions about Princess Diana's death as part of Operation Paget. 

"Why do you think the princess wrote this note, sir?" Charles was asked.

The royal replied, "I did not know anything about [the note] until it was published in the media."

"You didn't discuss this note with her, sir?" Stevens asked, to which Charles said, "No, I did not know it existed."

When asked, "Do you know why the princess had these feelings, sir?" Charles replied, "No, I don't."

"At the end of the day, he was incredibly cooperative because he had nothing to hide," Daily Mail late reported.
