Prince Harry, Duke of Sussex, Prince Harry, has revealed that his elder brother, Prince William physically once assaulted him.

The revelation was contained in Harry’s highly-anticipated autobiography “Spare” according to Guardian UK on Thursday.

The Royal spare, Harry said the Royal heir, William, grabbed him by the collar and threw him to the floor during a fiery argument over his wife Meghan Markle.

The Prince of Sussex said the argument occurred in 2019 in which his brother physically “attacked” him.

In an excerpt obtained from the book that will be made public on January 10, Harry recalled that the attack left him with noticeable injuries, including scrapes and bruises.

The argument allegedly broke out at his London home in 2019, during which William was said to have named Meghan ‘difficult’, ‘rude’ and ‘abrasive’ before tackling him to the ground.

Harry accused his brother of “parroting the press narrative” about his wife before they screamed at each other which resulted in a physical squabble, the “Spare” has revealed.

In one dramatic citation, Harry said that William “grabbed me by the collar, ripping my necklace, and…knocked me to the floor.”

“Spare” is a forthcoming memoir by Prince Harry expected to be in the public domain in five days.
