In an interview with the Daily Express, Irving suggested that the depiction of the brothers' relationship might be more severe than the reality. He emphasized, "But the link there is Diana. To me, she still looms over this whole rift."
Irving highlighted the noticeable "gulf" between the Windsors and the Spencer family, to which Princess Diana belonged, stating, "Harry is without any doubt a Spencer."
William, on the other hand, is navigating the challenge of embodying both the Windsor and Spencer identities.
"He’s trying to be a Spencer and a Windsor, and he’s doing very well at being a Windsor, but not very well at being a Spencer," remarked The Last Queen author.
Tensions between the brothers escalated after Prince Harry's sudden decision to step away from the Royal Family in 2020. Since then, the Duke of Sussex and his wife, Meghan Markle, have been vocal critics of the Firm, revealing family secrets, including personal conversations.
Royal author Omid Scobie, known for his close association with Harry and Meghan, asserted in his latest book, "Endgame," that there is "no going back" for the two brothers.
