Prince William 'drew a line in the sand' after the release of Prince Harry's explosive memoir, and royal commentators claim the Prince of Wales is now furious that King Charles III refuses to firmly back him against his younger brother.
The royal rift reached unprecedented levels following the January 2023 publication of Harry's book, Spare, which detailed a 2019 physical fight between the brothers at Nottingham Cottage over Meghan Markle. The book sold 1.43 million copies across the United Kingdom, United States, and Canada on its first day alone, becoming the fastest selling non-fiction book on record according to publisher Penguin Random House.
