An edition of the American animated TV series appeared to take aim at the couple.

The episode, called Worldwide Privacy Tour, featured a "prince of Canada" character and his wife who move into the fictional South Park.

The fictional couple were seen drawing attention to themselves and promoting a memoir, called Waaaagh.

There were also similarities with Harry's hair and beard and with an outfit which Meghan wore at Trooping the Colour in 2018.

Royal commentators in some sections of the media had suggested Harry and Meghan's lawyers were looking at the episode, but these claims have been dismissed.

A spokesperson for the Duke and Duchess of Sussex told People magazine: "It's all frankly nonsense. Totally baseless, boring reports."

Last month, it was revealed a Netflix series on Harry, 38, and Meghan, 41, was the streaming service's second-highest ranked documentary it had ever released.

The documentary's airing before Christmas came in the lead up to the publication of the duke's controversial memoir, Spare.

The autobiography became the fastest-selling non-fiction book in the UK since records began in 1998 following its release on 10 January.
