Meghan Markle and Prince Harry should be “very concerned” that their popularity is plummeting, according to a royal experts, as American media begins to pick the Duke and Duchess apart. The raunchy, and often satirical show South Park was the latest US household name to savage the Sussexes, depicting the pair as a whiny couple who loudly beg for privacy.

The episode follows the Prince and Princess of Canada, however the veil is thin. The prince has Harry’s red hair and has written a book titled “Waaagh” while the princess wears a dusky pink outfit similar to the outifit Meghan wore at the 2018 Trooping of the Colour.

The episode repeatedly slams the Sussexes, or rather the Prince and Princess of Canada, with one of the main characters, Stan, branding the cartoon equivalents a “dumb prince and his stupid wife”.

However, more than just being publicly mocked, royal experts have warned the Sussexes that the tide may be turning on them in the US as they become the butt of the joke.

Royal commentator Richard Fitzwilliams said the Sussexes should be “very concerned” after South Park “went for the jugular”.
