Prince Harry will be sidelined by Prince William and Prince Charles after the Queen’s death, the author says. Royal biographer Andrew Morton believes that Prince Harry has reached the bottom in the midst of a rift with his father and that he is the only queen for whom he still matters in the United Kingdom. The author of the recently published biography, the Queen, told Express.co.uk: “Harry’s main ally in the Royal Family is the woman that Diana called the ‘chief lady’, the queen. “When he leaves, he will have published his book, which will contain a strong enough attack on his father. “He is not talking to his brother, who will be the next Prince of Wales, so he will disappear into the shadows, he will be on the sidelines – something he can do as he pleases.” Harry’s memoirs, which will be released later this year, are a “definitive description of the experiences, adventures, losses and life lessons that helped shape him.” The book will reveal “Harry’s life to the public from childhood to today”.
