Prince Charles has denied claims he was the one that commented on Prince Harry and Meghan Markle’s son Archie’s skin colour.

American journalist and author Christopher Andersen wrote in his new book Brothers And Wives: Inside The Private Lives of William, Kate, Harry And Meghan that Charles had made the comment on the day Harry and Meghan’s engagement was announced back in November 2017, the Times reported.

However, a Clarence House spokesperson has since insisted: “This is fiction and not worth further comment.”

The book claims that Charles said to Camilla: “I wonder what the children will look like.”

The Duchess of Cornwall was said to have replied: “Absolutely gorgeous,” to which the book suggested Charles replied, “I mean, what do you think their children’s complexion might be?”

The book’s release comes after Meghan told Oprah Winfrey in a tell-all interview that aired earlier this year, “In those months that I was pregnant, we had those conversations about his title, his security, and how dark skin his might be.”

“Who was having that conversation with you?” Oprah asked.

But Meghan wouldn’t share which members of the family said those things, insisting: “That would be very damaging.”

When Harry joined the interview, Harry said it was a conversation “I am never going to share.”

ET Canada has contacted Clarence House and Harry and Meghan’s rep for comment.

Andersen then told Hoda Kotb and Savannah Guthrie on “Today” of the comments: “What I’m saying is that on the morning the engagement of Harry and Meghan was announced, in a very kind of benign way, Prince Charles started to muse on what their future grandchildren might look like.

“Here’s this beautiful, biracial American woman and the world’s most famous redhead. I’m a grandfather, of course we all do this, speculate on that. But it was turned into something very toxic, it was weaponized really, by the men in grey who run the palace organization.”

Andersen insisted on “Today” that he has multiple sources for all his reporting.
