Princess Diana’s brother Earl Spencer has finally disclosed the name of the person who was aware of his recently published book about his sister.

Speaking to the CBS Mornings, Earl revealed the name when he was asked whether Harry and Prince William knew about the book.

In response, William and Harry’s uncle claimed that he kept it a secret from everyone.

"I decided not to have anyone involved in the book," Earl Spencer said and explained that he did not tell family members about the memoir until shortly before its public release because he did not want anyone, particularly Harry, to think he had been involved.

The author further revealed that only his new wife Cat Jarman and the publishers were aware of "Swan Song: Diana, My Sister."

Moreover, the outlet also shared the clip on its X, formerly Twitter handle.

Princess Diana “was a really brilliant mother” who was completely her own person, her younger brother, Charles Spencer, tells the interviewer, the post reads.

“There was no one like her.”

It further said, “Spencer opens up about some of the revelations from his new book, “Swan Song,” and responds to Buckingham Palace’s statement about some of the allegations he makes regarding King Charles from the time of Diana’s death: ‘They have to gaslight. They have to, sort of, pretend there’s something wrong with my mind or my memory. There’s nothing wrong with either.”
