Prince Harry has denied claims his book will be published in November as planned, a royal source has reportedly claimed.
The Duke of Sussex has been working on the “intimate and heartfelt memoir" since 2020 with the help of ghostwriter JR Moehringer – a Pulitzer Prize-winning author.
The as yet untitled book had initially been pencilled in for an autumn 2022 release date.
However, royal insiders were apparently surprised that the memoir does not feature on a list of the publisher's upcoming books.
A November release date would see the book, that could reveal further details on a royal rift with the Sussexes, hit shelves just months after the Queen's death.
Tom Bower, whose biography of Meghan Markle was released this year, claims the Duke is however "insisting" it gets released this year.

He told GB news: "I am told tonight that Harry is insisting that his book is published in November.
"Apparently the publishers are not too certain, but he says if they don't publish it will be a breach of contract. That's what I'm told.
"It's extraordinary. But on the other hand it fits the bill, because Harry and Meghan's finances depend entirely on the book and on Netflix."
However, a source has since claimed the Duke denies this, reports Mail Online.
Publishing sources told the outlet it could be pushed back to 2023 to allow Prince Harry to write more chapters on the passing of the Queen.
A spokeswoman for Transworld, part of Penguin Random House, previously said: “We don’t put every book on the list so there is nothing to be extrapolated from that.”
Harry, 37, has yet to shed much light on the contents of his memoir, although he did consult the Queen about the project before going public with an announcement last summer.
“I’m writing this not as the prince I was born but as the man I have become," he said of the upcoming book.
Harry criticised his childhood and upbringing in an interview with the Armchair Expert podcast last year, while his interview alongside wife Meghan Markle with Oprah Winfrey also put a strain on several royal relationships after the pair made accusations of racism and claimed they had been financially cut-off.
Palace aides reportedly fear Harry's book will open another can of worms, with his strained relationship with stepmother Camilla, Duchess of Cornwall, a potential source of more negative headlines.
The Mirror has contacted Transworld books at Penguin for a comment.
