Duke of Sussex, Henry Charles Albert, has disclosed that his brother, William Arthur Louis knocked him on the floor during a confrontation in London in 2019.

In an exclusive report, the Guardian UK obtained a copy of Mr Henry’s memoir, where Mr Harry disclosed that he was physically assaulted by his brother, now the prince of Wales, in a fallout over the younger prince’s relationship with Meghan Markle.

Mr Harry writes that he offered his brother a glass of water while the argument was heated and said: “Willy, I can’t speak to you when you’re like this.”

“He set down the water, 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,” he writes.

He further disclosed that Mr William urged him to hit back, citing fights they had as children, but he refused to do so.

Mr Harry also said that his brother called Ms Meghan “difficult, rude and abrasive,” which was an unacceptable reiteration of the media’s narrative about his wife.

Mr Harry’s memoir, Spare, is scheduled for release next week and is anticipated by many who are eager to take a peep into the life and struggles of the British royalty who by culture draws his relevance from being circumstance-bound alternative to his older brother.
