Prince Harry claims he knew immediately he and brother William would have a heated row when he arrived at his door before he broke his necklace and knocked him to the floor.
In his new book, Spare, the Duke of Sussex recounts the alleged physical attack at his London home in 2019 after the future king called wife Meghan Markle "difficult" and "abrasive".
Harry felt his older sibling was simply parroting "the press narrative" before the confrontation escalated.
