Prince Harry, Meghan Markle 'On A Mission To Damage' King Charles' Coronation, Royal Expert Claims

Prince Harry's upcoming memoir has his father King Charles III and older brother Prince William "worried," a royal expert has claimed.

Last week, Penguin Random House announced that the Duke of Sussex's highly anticipated tell-all is titled "Spare" and that it will be released in January 2023, months before King Charles' coronation. Prince Harry and his wife Meghan Markle also have a docuseries with Netflix coming out, but a release date has yet to be announced.

Neil Sean, a royal and entertainment reporter, slammed the Sussexes on his YouTube channel, claiming that "they're on some kind of mission once again to make sure they damage the forthcoming coronation next spring for King Charles III."

Sean, who has been featured on NBC News, Fox News and Access and has contributed to numerous daily newspapers, including the Daily Mail, claimed that King Charles and Prince William are not very concerned about their portrayals in Prince Harry's upcoming book but that they are worried about what he might say about Queen Elizabeth II.

"Both senior royals are not too concerned about their portrayal because they know the public are educated people who will know that there's a vendetta there. [Prince Harry has] to say certain things in order to make money to reclaim that boost from Penguin Random House," he claimed on his video. "[But] they are worried if [Prince Harry] has said anything negative about our late monarch."

Sean pointed out that Prince Harry went on TV and "openly claimed that the Queen spoke to him and him only exclusively as only she could about things."

"This is truly what set off that lightbulb moment within royal circles. Because if Harry's claiming that sort of situation, what could he possibly claim now with the demise of our late monarch?" he said.

Following a visit to Queen Elizabeth in the U.K. in April, Prince Harry said in an interview with NBC News' "Today" show that he and his grandmother "have a really special relationship" and that they "talk about things she can't talk about with anyone else,"

Sean said he believes Prince William will be "really" angry if Prince Harry writes anything that will "decimate" their grandmother's legacy.

"Once it's in print, there's simply no going back," the royal expert said. "But trust me, the King and the Prince of Wales are awaiting this eagerly along with their many esteemed lawyers."

International Business Times could not independently verify Sean's claims.

Following Queen Elizabeth's death on Sept. 8, the release of Prince Harry's memoir, which was initially set to hit shelves in November, was pushed back to next year out of respect for his grandmother.

"Of course, the Queen"s passing was something that was always speculated on when we started working on the book ... when it comes down to it, there is absolutely no way the book can come out this year," an unnamed insider told Page Six at the time. "You only have to look at the royal family to see how emotional they are. This is a matter of respect for Her Majesty — as Prince Harry's grandmother and as his Queen."

At the time, it was speculated that Prince Harry may use the delay to remove some "truth bombs" about his father and other members of the royal family.

However, one unnamed source told Page Six that the Duke of Sussex "would never write anything bad about the Queen. He always has had the utmost love and respect for her."

But an unnamed friend of King Charles' wife Queen Consort Camilla told The Daily Beast that Prince Harry and Markle likely won't be invited to the monarch's coronation in May 2023 if the prince attacks his stepmother in his memoir.

"Almost everything Charles has done over the past 20 years has, in one way or another, been about getting Camilla accepted by the public," the friend claimed. "He loves her. He is incredibly protective of her and he couldn't do it without her. Even the queen finally accepted that. It is one thing for Harry to attack Charles, he can take it on the chin, but if Harry forces him to choose, by laying into Camilla in his book, I have no doubt he will choose Camilla."
