Bookshops across London opened at midnight to meet demand for Prince Harry's memoir after it officially went on sale.

Fans queuing to buy a hardback copy described wanting to hear the story “from the horse's mouth”.

It follows the chaotic launch of Spare with multiple leaks and copies being made available in Spain last week.

Waterstones says Prince Harry's book has been one of its “biggest pre-order titles for a decade”.

The booksellers opened their flagship Piccadilly branch early on Tuesday in expectation of high customer demand, as the book was published around the world in 16 languages.

Branches of WH Smith in locations including Euston, Victoria, Heathrow and Gatwick were also among those to extend their hours for the release.

The memoir is already top of the best sellers in the UK for online retailer Amazon, after days of headline-grabbing revelations from leaks - ranging from how Prince Harry lost his virginity to claims that Prince Harry was attacked by his brother, Prince William.

The 410-page memoir, revealing the conflict and personal tensions inside royal palaces, shows Prince Harry's version of growing up and then falling out with the Royal Family.

So far Buckingham Palace and Kensington Palace have not responded.

But the claims in the book include that Prince Harry begged his father not re-marry, that he killed 25 Taliban fighters while serving in Afghanistan, that he took psychedelic drugs, partly in response to panic attacks, and that Meghan and Catherine had a difficult relationship.

A major theme in the book is the sense of unresolved grief for the loss of his mother, Princess Diana, with Prince Harry saying he had a “post-traumatic stress injury”.

The press are held responsible for pursuing Diana and Prince Harry said in one of several interviews promoting the book that it would be his “life's work” to change the media landscape.

There are also unexpected details such as Prince Harry and Prince William calling each other “Harold” and “Willy”, that Harry used to get his clothes at discount outlet TK Maxx and watched a lot of Friends on television.

Prince Harry recalls he first found out from the BBC website that the late Queen Elizabeth had died, rather than from his family.

Members of the Royal Family have been omitted from the acknowledgements section of the book. Instead, the duke gives special thanks to friends in the UK “who stuck by” him “amongst the fog”, adding: “Next round's on me.”

Harry also says his therapist helped him “unravel years of unresolved trauma”.

The revelations about tensions with the Royal Family, including Camilla, the Queen Consort, and the Prince and Princess of Wales, have provoked much controversy.

But Prince Harry said the divide between him and his family “couldn't [have been] greater before this book" when asked if its publication would help with, or hinder, the chance of reconciliation.

“There are things that will still anger me, but I'm not angry any more, because I am exactly where I am supposed to be,” he told Good Morning America. (BBC)
