Prince Harry and Meghan Markle's feud with the Prince and Princess of Wales will "never be healed", a royal author has claimed.
William and Kate were both at King Charles' Coronation along with Harry - although Meghan stayed at home with her children Prince Archie and Princess Lilibet.
It was the first time the two warring brothers had been seen at the same event since the release of Harry's controversial memoir Spare.
