People Editorial Guidelines Updated on October 8, 2022 06:06 PM Share Tweet Pin Email Prince Charles (now King Charles III) was questioned by the U.K. police in 2005 about the death of his ex-wife, Princess Diana, according to a report. The probe was part of Operation Paget, the investigation into the various conspiracy theories surrounding Diana's death, launched by the British Metropolitan Police in 2004. John Stevens, former head of Scotland Yard, told the Daily Mail that he spoke to then-Prince Charles about a note that Princess Diana wrote in 1995, which read: "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. Charles and Diana divorced in 1996. After the note became public in 2003, Prince Charles was interviewed at St. James's Palace as a witness two years into the investigation. "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 told the outlet. "We found no other evidence to support the scenario suggested in Diana's note." Prince Charles Told Princess Diana He Didn't Love Her the Night Before Their Wedding, Her Friend Claims "We were left with the note, which, in itself, was not enough to make Charles a formal suspect," he continued. "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." Prince Charles and Princess Diana.

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."

Although Prince Charles cooperated with the investigation, his father, Prince Philip, declined to assist in the investigation.

PA Images Princess Diana's note was written around the time she did her famous BBC Panorama interview with Martin Bashir. An inquiry conducted by former supreme court judge John Dyson found in 2021 that Bashir used "deceitful methods" to secure the interview in 1995 by commissioning fake bank statements.

Stevens regretted that he and his officers did not interview Bashir. "If there'd been an allegation then that Bashir had produced allegedly fake documents to Princess Diana, which is a criminal offense, we'd have investigated it. My goodness me, we would have done," he said. "But this has only come out recently, which is unfortunate."
