  • According to reports, King Charles blamed his former private secretary for his confession.

  • The marriage of Charles and Princess Diana was still going on at the time.

  • The author said it ended the private secretary's career.

According to a new book, King Charles once admitted to being unfaithful to Princess Diana in a TV interview.

The Prince of Wales was invited to be interviewed by Jonathan Dimbleby in 1994. He and Princess Diana had been apart for two years. Rumors about the nature of his relationship with his wife were addressed during that interview.

The author of "Courtiers: The Hidden Power Behind the Crown" said that the confession caused "untold reputational damage." It was the basis for Richard Aylard to leave his position in 1997.

Insider asked Richard Aylard for comment. Buckingham Palace didn't reply immediately.

Insider previously reported that Charles told Dimbebly that he was faithful and honorable to Diana until it became irretrievably broken down.

The backlash against Charles' confession came from people in the royal family. Sally Bedell Smith's book, "Prince Charles: The Passions and Paradoxes of an Improbable Life," was shared in a new book by the author.

Another dinner guest said that the man pointed at his private secretary and angrily said, "He made me do it!" One dinner guest said that it was a very unattractive moment.

It would be the beginning of the end of Richard Aylard's career. He wrote that Aylard had been brought on to help Diana adjust to her role in the public eye and had been tasked with the responsibility of bridge the gap between the princess and Charles as their marriage deteriorated.

"Charles's confession of adultery, which was confirmed the following day by Aylard at a press conference, would cause the prince untold reputational damage."

The author said that it was the right move to convince Charles to confess his infidelity.

Charles was able to lie, tell the truth or not. He would be caught out one day if he lied. The tabloids would keep digging if he didn't answer the question.

Low wrote that his days were numbered under Charles because he didn't like him. According to Low, Aylard's replacement, Mark Bolland, had already been hired and was given the task of getting rid of him.

According to an unnamed source interviewed by Low, the final straw in her first marriage was Charles' confession.

The Dimbleby exercise was what ended her marriage. The individual said that there was a beef with Richard.
