Prince Harry has enough material for an entire new book following Spare, he has revealed, saying he only kept the content out for fear of upsetting Prince William and King Charles.

The Duke said shortly after the book’s publication that “there could have been two books”, telling the Telegraph: “The hard bit was taking things out.

“There are some things that have happened, especially between me and my brother, and to some extent between me and my father, that I just don’t want the world to know. Because I don’t think they would ever forgive me.”

A royal historian has since argued that Harry’s decision to “air his dirty laundry” has severely damaged the monarchy’s public perception and impacted their image of being the “best of British family life”.

Speaking on the Mirror’s Pod Save The King podcast, Dr Owens, author of the new book After Elizabeth: Can the Monarchy Save Itself?, said: “Originally King Charles III’s reign was going to be based around him being supported by his two trusty lieutenants – William and Harry. But when that went so disastrously wrong in early 2020 because of Harry and Meghan’s decision to leave Britain, it really put paid to that vision of the family monarchy.”
