Prince William and Prince Charles were reportedly dismayed at Prince Andrew's role in accompanying Queen Elizabeth II to Prince Philip's memorial service.
Since quitting his royal duties last year, Prince Harry will have his first visit to Britain for Prince Philip's funeral without his wife, Meghan Markle.
Palace insiders have advised Prince Harry to fly home for Prince Philip amid the elder royal's hospitalization. Royals are reportedly so concerned with the Duke of Edinburgh's health that Prince Harry has been told to return to the U.K. to say goodbye to his grandfather.
