Christopher Andersen alleges in his book that Charles made the comment on the day Harry and Meghan’s engagement was announced in November 2017.
In Brothers and Wives: Inside the Private Lives of William, Kate, Harry and Meghan, he writes the prince said to the Duchess of Cornwall: “I wonder what the children will look like?”, the New York Post’s Page Six website reported.
When Camilla replied: “Absolutely gorgeous, I’m certain,” the book claims Charles went on to say: “I mean, what do you think their children’s complexion might be?”
A Clarence House spokesman said: “This is fiction and not worth further comment.”
Harry and Meghan claimed during their Oprah Winfrey interview that when Meghan was pregnant with Archie, a member of the royal family raised “concerns... about how dark his skin might be”.
