Prince Harry has finished writing 'intimate and honest' memoir of his childhood and life with Meghan - EXCLUSIVE

Prince Harry has finished writing his "intimate and heartfelt" memoir, Yahoo News UK can reveal.

In what has been billed as the “definitive account” of the Duke of Sussex’s life, the book was announced last summer following a rollercoaster 18 months which culminated in Harry and Meghan stepping back from their roles as senior royals and moving to the US.

The contents of the memoir have been the subject of much speculation.

According to publisher Penguin Random House, it will be “intimate and heartfelt” and cover Harry’s time in the public eye, from his childhood up until his marriage with Meghan and starting life as a family in the US.

Some royal commentators have warned the book could destabilise his already fractious relations with his father and brother. Royal expert Robert Jobson told MailOnline it will cause “mayhem amongst the House of Windsor”.

Jobson added: 'If Harry, which seems inevitable, goes into detail about mental health issues involving his wife and alleged racism at the heart of the royal family, it will be hugely damaging to the House of Windsor and the Monarchy as an institution.”

However, according to royal author Omid Scobie, sources close to Harry have insisted the book does not take potshots at his family.

Writing in his latest column for Yahoo News UK, Royal Executive Editor Scobie says: “His forthcoming memoir—which is now finished and has completed legal checks—will no doubt invite some of it [drama] in, even if, as sources have told me over the past year, it doesn’t include those much-reported “attacks” on his family.”

Harry himself has said of the memoir: “I’m writing this not as the prince I was born but as the man I have become."

The book is one of multiple projects the Sussexes are working on.

As revealed by Scobie in his column, Harry is also believed to be working on his own podcast, though details of the project have yet to be made public.

Separately, in March, Meghan unveiled her first Spotify series – a podcast about female stereotypes, in which she vowed to investigate “labels that try to hold women back”.

Archetypes will launch this summer, hosted by Meghan who will speak to historians, experts and woman who have experienced being typecast.

In a trailer released by Archewell Audio, male voices are heard saying derogatory remarks about women including “she’s a slut” and “a little emotionally unstable”.

Meghan follows the excerpts, saying: “This is how we talk about women: the words that raise our girls, and how the media reflects women back to us… but where do these stereotypes come from? And how do they keep showing up and defining our lives?”

In May, Netflix announced it had cancelled development of Pearl, an animated series created by Meghan, in a cost-cutting move.

The screaming giant did confirm it planned to continue work on a number of projects with Harrying Meghan’s Archewell Productions company, including a documentary series called Heart of Invictus.

Harry and Meghan’s relationship with senior royals has been cast back into the spotlight in recent days.

According to unnamed sources cited in a new book, the Queen is alleged to have said “thank goodness Meghan is not coming” to the Duke of Edinburgh’s funeral.

The claim was made in biographer Tom Bower’s book “Revenge: Meghan, Harry And The War Between The Windsors”, which is being serialised in the Times and Sunday Times.

Buckingham Palace, which does not comment on individual books, declined to comment on the story.

However, sources close to the Queen question whether she would have anything other than Philip on her mind on the day of the funeral.

The book, which makes a series of controversial claims, also says the Prince of Wales opposed a “demand” by the Sussexes to appear with the Queen on Buckingham Palace’s balcony” during the Platinum Jubilee celebrations last month.

Clarence House and Harry and Meghan have declined to comment on the book.
