In his new book about life as a member of the royal family, Prince Harry of Great Britain says he was once knocked down in a fight with his brother, Prince William. Harry’s book, Spare came out this week in Spain. It is supposed to be put on sale in other countries on January 10. The prince is the youngest son of Britain’s King Charles III and Princess Diana. His older brother, William, is next in line to become King after their father. The name of the book comes from Harry’s position in the royal family. He is the spare, or extra, son. The 38-year-old Harry made news in 2020 when he and his wife, Meghan Markle, decided to leave the royal family and move to California. The book tells of a 2019 argument between the brothers that became a physical fight at Harry’s home in London. Harry wrote that William called Meghan difficult, rude and abrasive. In the argument, Harry wrote, William grabbed him by the shirt, broke his jewelry and knocked him down. He had “scrapes and bruises” after falling into the food bowl of the dog and breaking it. Harry said William told Harry to fight back, but he would not. William later apologized, Harry wrote.
