When it comes to his son, Prince Harry, King Charles III is not taking any chances.

If the Duke of Sussex attacks Queen Consort Camilla in his upcoming controversial biography, the incoming king has allegedly promised to bar him from his coronation the following year.

According to Page Six, King Charles III is still concerned about his son, who may have Camilla on his mind in his upcoming book, due out next year.

The coronation of King Charles III is scheduled for May 6, 2023. Though there is no official release date for his son’s biography, the future king is said to be planning at least one chapter on Camilla.

According to an insider, the King may be able to withstand his son’s insults, but if Prince Harry forces him to choose by slamming the Queen Consort in his book, King Charles III will choose his wife.

Another royal source stated that Prince Harry and Meghan Markle are on a “tentative list” for the coronation, implying that the King is “leaving the door open to receive the call” or be completely excluded.

Since he and the Duchess relinquished their royal duties in 2020, the Duke of Sussex’s book may jeopardize his chances of ever returning to the royal fold, particularly in an official capacity.

Former Vanity Fair editor Tina Brown believes Prince Harry’s return to the UK in the aftermath of Queen Elizabeth II’s death was a “great opportunity” to capitalize on, as the British appreciated the sense of togetherness and having him and Prince William back together.

However, she warned that there could be no trust until Prince Harry makes his book and tell-all interviews public.

The book was supposed to be published in November, but it has been delayed until next year. According to current reports, the book could be released around Easter, giving the Duke more time to include details about his grandmother’s death and funeral.

Regarding the book’s delay, another royal author, Tom Bower, stated that it would simply contain more information about how they were rejected as well as “the remainder of the venom against the royal family.”

Prince Harry signed a $20 million deal with Penguin Random House in July 2021.
