Prince William’s temper reportedly “terrifies” King Charles.

According to royal author Christopher Andersen, the 43-year-old is “capable of great bellowing tantrums.”

William’s brother Prince Harry also wrote of his brother’s short fuse in his 2023 memoir Spare.
Prince William has a famously warm rapport with his wife Kate Middleton and the couple’s three children, but according to royal biographer Christopher Andersen, his relationship with his father, King Charles, can be more complicated. Andersen, who recently published a book about the Princess of Wales, said William is “capable of great bellowing tantrums” and sometimes “terrifies” the 77-year-old monarch.

“When he gets frustrated, he does resort to shouting [at the king],” a former staff member of Highgrove House, Charles’s country estate, told Andersen, per Page Six. “William has a huge, booming voice. Much louder than his father’s, so it’s not something you soon forget.”

Andersen’s new biography, Kate! The Courage, Grace, and Power of the Woman Who Will be Queen, dropped on Tuesday, May 5. The author is far from the first royal insider to put a spotlight on the future king’s temper, however. William’s younger brother Prince Harry recalled getting into a heated argument with him regarding Meghan Markle in his 2023 memoir Spare. (Recall that William reportedly refused to “roll out the red carpet” for his sister-in-law.)

According to the Duke of Sussex, the conflict escalated until William “grabbed me by the collar, ripping my necklace, and … knocked me to the floor.” Harry landed on a dog bowl, “which cracked under my back, the pieces cutting into me.” The brothers are currently estranged and have hardly spoken since Harry and Meghan’s departure from the U.K. in early 2020.

As for Charles, he too “has a Vesuvius temper,” Andersen said. Apparently the apple doesn’t fall far from the tree.
