Prince Harry and wife Meghan plan to tell their extraordinary story in a book penned by sympathetic journalists.

Harper Collins UK has announced Finding Freedom: Harry and Meghan and the Making of a Modern Royal Family will be published in Britain and the Commonwealth on August 11.

The book will be published in the US the same day by HarperCollins-owned Dey Street Books.

Authors Harper's Bazaar royal editor Omid Scobie and Elle magazine royal correspondent Carolyn Durand said they aimed to capture "the real Harry and Meghan" and "finally present the truth of misreported stories" about them.

The publisher said the book would tackle "the many rumours and misconceptions that plague the couple on both sides of the pond".

It said the authors had been given "unique access" and the cooperation of those closest to the couple.

Freed from the constraints of life as full-time royals, the announcement comes two weeks after Harry and Meghan said they would no longer cooperate with several British tabloid newspapers because of what they called "distorted, false or invasive" stories.

Meghan is suing publisher Associated Newspapers for invasion of privacy and copyright infringement over a series of articles in the Mail on Sunday that reproduced parts of a letter she wrote to her father, Thomas Markle.

Harry, who is a grandson of Queen Elizabeth II and sixth in line to the British throne, married the American actress at Windsor Castle in May 2018, in a lavish ceremony watched around the world.

The couple later said they found the scrutiny they received from the British media intolerable and claimed it tipped over into harassment.

In January, they announced they planned to quit as senior royals, seek financial independence and move to North America.

The split became official at the end of March, and the couple have relocated to the Los Angeles area, where Meghan was raised.
