Scobie had previously told The Times: “To deliberately snub your sister-in-law … I don’t think it left a good taste in the couple’s mouths.”
The authors also described a culture of gradually growing bitterness and resentment between the Sussexes and other members of the royal family.
They say the Sussexes felt their complaints were not taken seriously and that other royal households were leaking stories about them to the press.
The authors write: “There were only a handful of people working at the palace whom they could trust… A friend of the couple called the old guard ‘vipers’.
“Meanwhile, a frustrated palace staff member described the Sussex team as the palace’s ‘squeaky third wheel’. ”
Meanwhile, the book claims that the official photograph of Prince Charles’ 70th birthday with his family was a “nightmare” to plan because his sons were blowing “hot and cold” with their father.

Behind the prince and his wife were William and Kate, the Duchess holding Prince Louis, Harry and Meghan.
The book also claims that Charles and Harry’s relationship was more complicated than a traditional father-son bond.
The authors wrote: “‘Although Charles may be Harry’s father, he is also their boss, and that makes the relationship complex for several reasons,” a source added.
“‘Charles is extremely focused on his public image, and there were times when Harry felt that had taken precedence over everything else,” the source said. ”
The book looks back on the events of the past few years, since the couple’s first meeting and love, their decision to step down as royals in order to have financial freedom and the first weeks of the coronavirus lockdown.
But a spokesperson for the Duke and Duchess of Sussex distanced the couple from the book, saying: ‘The Duke and Duchess of Sussex were not interviewed and did not contribute to Finding Freedom.
“This book is based on the authors’ own experiences as members of the Royal Press and their own independent reporting.
Clarence House and Kensington Palace declined to comment.
