Prince Harry released a neverending wave of allegations and revelations about the royal family when he debuted his tell-all memoir, Spare, in January.

The book covers a wide range of subjects from his fractious relationship with his brother Prince William to the struggles after his mother Diana’s death in 1997.

His sex life, drug use and time served in the army are also covered in a memoir that goes into uncomfortable levels of detail.

Buckingham Palace declined to comment about any of the contents of the book at the time of its release.

Here are the claims and revelations made in the book:

Harry wrote: “(William) called me another name, then came at me. It all happened so fast. So very fast. He grabbed me by the collar, ripping my necklace, and he knocked me to the floor.

“I landed on the dog’s bowl, which cracked under my back, the pieces cutting into me. I lay there for a moment, dazed, then got to my feet and told him to get out.”

Prince Harry has also spoken of the “red mist” that came over his brother during this altercation.

Harry told ITV’s Tom Bradby: “What was different here was the level of frustration, and I talk about the red mist that I had for so many years, and I saw this red mist in him.”

The Duke claimed William urged him to hit back, citing fights they had as children, but Harry refused and his brother left before returning, looking regretful and apologising.

The alleged altercation took place at Harry’s then home in Nottingham Cottage, on the grounds of Kensington Palace, when William is said to have called Meghan “difficult”, “rude” and “abrasive”.

Harry told him he was parroting the press narrative about his wife.

The duke claimed William told him he did not need to tell Meghan about the confrontation.

Harry wrote that he told his therapist first and his wife later after she noticed the scrapes and bruises on his back. “She was terribly sad,” he said.

Brothers’ nicknames revealed
William and Harry’s nicknames for each other were revealed in the Duke’s account of the alleged altercation.

Harry wrote that he gave his brother a glass of water and said: “Willy, I can’t speak to you when you’re like this.

William told him “I didn’t attack you, Harold.”

Harry claims William and Kate encouraged him to wear Nazi uniform
Harry sparked outrage in 2005 when he wore a Nazi uniform complete with a swastika armband to a fancy dress party.

But in the book, he claims he phoned William and Kate to ask them whether he should choose a pilot’s uniform or a Nazi one for the fancy dress party.

He says the couple urged him to wear the latter, and both howled with laughter when he went home and tried it on for them.
