The Duke of Sussex’s complaints about his upbringing are no different to his father’s criticism of his own parents in an authorised biography by Jonathan Dimbleby, sources close to him have suggested. The Duke, 36, implied in a podcast that he had been failed not only by the Prince of Wales but through association, by the Queen and the Duke of Edinburgh too. He said his father had treated him “the way he was treated” as he revealed that he moved to the US to "break the cycle" of "genetic pain" for his own children. The comments were met with bewilderment by the Royal family, who considered it a betrayal. Aides said he had shown a “woeful lack of compassion” for his own family and questioned why the Sussexes continued to use their royal titles when they appeared so disillusioned with the institution. However, sources close to the Sussexes pointed out that Prince Charles had lifted the lid on his own unhappy childhood in Mr Dimbleby’s 1994 book, The Prince of Wales: A Biography, with which he cooperated extensively. It came as it emerged that the Duke will talk about his mother’s death and the experience of having to walk behind her coffin at her funeral in his new Apple TV mental health series. The five-part documentary, called The Me You Can’t See, will be released on Friday. A trailer showed footage of Prince Harry, then 12, taking part in the procession before the funeral of Diana, Princess of Wales, in 1997. The Duke is then shown looking upset, his hand shaking as he holds it to his mouth.
