The Duke of Sussex has been open about his relationship with his father, the Prince of Wales, in recent months.
In his interview with Oprah Winfrey in March 2020, Prince Harry admitted things were strained between them, saying there is "a lot to work through" with Prince Charles.
And more on his Apple TV+ series in May, The Me You Can't See, Harry said: "My father used to say to me when I was younger, he used to say to William and I, 'Well, it was like that for me, so it's gonna be like that for you.' That doesn't make sense. Just because you suffered, it doesn't mean that your kids have to suffer. In fact, quite the opposite. If you suffered, do everything you can to make sure that whatever experiences, negative experiences that you had, you can make it right for your kids."
