According to Battle of Brothers: William and Harry — the Inside Story of a Family in Tumult, a book published by Robert Lacey, one of the most explosive moments between William and Harry was because of the Duchess, who allegedly mistreated staff at Kensington Palace.
William reportedly “went ballistic” when he heard of Meghan’s “bullying allegations.” Once notified, he immediately called Harry to discuss the matter, which infuriated his brother so much that he turned his phone off.
The insider spoke with In Touch about William’s “regrets” over Harry and Meghan.
