He told Us Weekly: "I was able to trace this back to a comment that was made by Prince Charles to [Duchess] Camilla on the day that the announcement of Harry and Meghan’s engagement was made.
"And what he did was casually turn to her like any grandparent to be would do and say, ‘I wonder what their children will look like, hair color, eye color, complexion.’
"He did it fondly, but the problem is it was… misconstrued, contorted over a period of time by the bureaucrats and the palace – the people who [Princess] Diana used to call the ‘men in grey’ – and they really weaponized that and turned it into something that was quite nasty by the time it reached Harry’s ear."
Prince Charles hit back at the allegations made by Mr Andersen and referred to the story as "fiction" and "not worth further comment".
