The feud between the Royals and Duke and Duchess of Sussex Prince Harry and Meghan Markle continues, this time in light of an alleged alternation between brother Prince Harry and Prince William, as revealed in Harry’s highly anticipated autobiography, ‘Spare’.

According to The Guardianwhich was granted access to a pre-launch copy of the book, Harry details the altercation in great length.

The attack happened in 2019 back when Harry and Meghan were living at Nottingham Cottage on the grounds of Kensington Palace. William came to visit Harry – he was, Harry says, already “piping hot” – to discuss the “situation” with Meghan. Harry alleges William called  Meghan “difficult”, “rude” and “abrasive”.

The conversation naturally escalated from here, Harry writing that William “grabbed me by the collar, ripping my necklace, and … knocked me to the floor”.

“It all happened so fast. So very fast,” Harry writes in the book, as told by The Guardian. “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.” Harry says William left and later returned to apologise to his brother, looking “regretful”. But as he left for the second time, Harry writes that William turned to his brother and allegedly said “You don’t need to tell Meg about this.”

The extraordinary passage is but one encounter mentioned within the new autobiography, which will be published worldwide next week. The backlash for the British royal family amid the book’s release is inevitable, especially since the family are only just recovering from the negative press surrounding the Harry and Meghan Netflix documentary, which aired in December 2022.

The title of the autobiography comes from an old saying in royal and aristocratic circles; a symbol of hierarchical procedures. The first son is an heir to titles, power and fortune, and the second is, therefore, a spare should anything happen to the firstborn.

Ahead of the book launch, two interviews with Harry are set to be broadcast in the UK and US this weekend, with ITV News at Ten and CBS 60 Minutes.
