Prince Harry is "desperately" trying to make changes to his tell-all memoir following the Queen's death, a source has claimed.
The "intimate and heartfelt" book, which was due to be released by Penguin Random House in December, is set to be delayed because of the royal mourning period.
It is now likely to be published next year, with senior royals including King Charles and Prince William said to be "increasingly uneasy" about the content of the memoir.
An insider has now claimed the Duke of Sussex is "desperate" to get the book "refined" in the light of his grandmother's passing, but warned that it "might be too late".
A source told The Sun on Sunday : "Harry has thrown a spanner in the works as he is desperate to get it refined in the light of the Queen’s death, her funeral and his father Charles taking the throne.
"There may be things which might not look so good if they come out so soon after the Queen’s death and his dad becoming King.
"He wants sections changed. It’s not a total rewrite by any means. He desperately wants to make changes. But it might be too late."
The insider also claimed the publishers paid £18.4million ($20million) up front for the book, but were "disappointed" by the first draft because it apparently focused on mental health issues more than they wanted.
Prince Harry has vowed that the book will be a "truthful and wholly accurate" account of his life - with the announcement of the novel sending a "tsunami of fear" through royal circles.
The Duke and his wife Meghan are heading back to the US following the Queen's funeral on Monday, with efforts made "on both sides" to heal rifts with their royal relatives, according to a friend.
The death of the monarch brought Charles, William and Harry together once again as they mourned and walked behind her coffin in several processions - and attended her funeral with their wives.
Speaking after the funeral, TV host Gayle King, who is known to be close to Meghan and attended her baby shower in New York, said: "There have been efforts on both sides … to sort of make this right.
"'Big families always go through drama, always go through turmoil. It remains to be seen — are they going to be drawn closer together or are they going to be drawn apart?
"I have no idea, I have no inside information on that, but I will tell you this: It was good to see Harry standing with his family."
