If Prince Harry does not want to face another court battle, this time against his own family, he will have to be extremely careful what he says in his memoir.

The royal family is thought to be worried about the contents of the Duke of Sussex's planned book. There are concerns that he may publicly humiliate Camilla and smear his father, Prince Charles.

Queen Elizabeth's Lawyers Allegedly Warn About Prince Harry's Memoir

According to The Telegraph's Associate Editor Camilla Tominey, despite his assurance that it will feature "wholly honest" stories of his life and experiences, he would still need to be "very very careful." After describing it as a "sensitive" memoir, she believes he must ensure that it is legally sound.

Tominey said this step is "a message to America to say don't think you can just write anything that you like as you said at Oprah Winfrey without being challenged on it, without offering a right of reply."

The book's contents might be altered as a result of the claimed warning from Queen Elizabeth II's attorneys. It might change the title to become "more tepid than we anticipated."

Penguin Random House, the Duke of Sussex's publisher, on the other side, wants an explosive to exposé . It becomes a problem and may make for unpleasant reading for the Royal Family, according to Tominey, who hopes that Queen Elizabeth II's Platinum Jubilee celebration will be as successful as the one in 2012 so that any negative attention around the biography would be overshadowed.

However, there is still fear that Prince Harry may ruin the family's reputation if he decides to unleash a slew of bombshells in his book in the autumn, and they are legally secure, so he may publish them without facing too much opposition. Regardless of the book's conclusion, she counseled the duke to avoid upsetting Queen Elizabeth II because of her weak health, according to Geo News.

Prince Harry Won't Return to UK for Prince Philip's Memorial Service

A representative for the Duke of Sussex stated on Friday that he will not be attending his grandfather Prince Philip's funeral ceremony in the United Kingdom. The decision comes amid a court tussle between the prince and the Home Office concerning his personal safety. Harry's legal team told a court last month that the Duke does not feel secure bringing his family to the United Kingdom without police protection.

Prince Harry will not attend Westminster Abbey with the rest of the Royal Family on March 29, but he will pay a visit to the Queen as soon as possible, according to a representative for the royal family.

Despite his departure from the Firm with his wife Meghan Markle in 2020, the Duke's connection with his grandmother is thought to have remained tight. There were rumors at the time that Prince Harry's decision to stand aside from his position as a senior royal had "blindsided" the Queen, as per Express.

In his new memoir, Prince Harry is said to have avoided criticizing the Queen. According to their friend and unofficial biographer Omid Scobie, he is about to release a tell-all book that will be his and Meghan Markle's "finale moment."

Many royal watchers were anxious about the contents of the book, which is expected to be released later this year. It was originally speculated that it would show the Prince's actual sentiments toward his stepmother Camilla while others speculated that it would "shake the monarchy to its core."

Prince Harry and his grandmother have always had a strong relationship, and royal watchers assume that any admissions he makes would exclude her. During Prince Harry and Meghan's contentious Oprah interview, he expressed his admiration for his grandmother and stated that he had just talked with her. Meanwhile, his wife spoke about how much she enjoyed being in the Monarch's presence, Mirror reported.
