Richard Fitzwilliams, a royal scholar, has just issued a warning to Prince Harry about his influence on his father's legacy.
The entire interview occurred with Fox News Digital, and he clarified his views.
According to the analyst, "Charles' reign is not being overshadowed by the feud," but there is a strong possibility of it "being damaged by it because of the huge amount of publicity."
"In his latest interview, Harry appeared furious and gutted... It would be a major issue for the royal family if he and Meghan launched more attacks."
However, this conduct "has become a familiar pattern for the 76-year-old monarch," according to the expert.
"Two years after his coronation, his reign is shaping up as both eventful and oddly unchanging in its core narrative: that of a beleaguered father managing a messy brood."
Ms Fitzwilliams even warned the monarch at the end, saying, "Unless Charles finds a way to heal that rift, it could define his reign, undercutting the messages of tolerance and inclusiveness that he has long championed."
