Prince Harry and Meghan Markle were issued a scathing five-word warning by a PR expert who called them out on making “the same mistakes all over again” and urged them to “step out of the deep ghetto” and “start again”.

The Duke and Duchess of Sussex have seen their popularity plummet over the years with the latest Ipsos poll, published last week, revealing that they still remain among the least popular royals when it comes to the public’s perception of the Royal Family.

Prince Harry is liked by less than three in ten Brits (28 percent) and disliked by nearly half (48 percent), while his wife is only liked by 21 percent and disliked by 53 percent.

Mark Borkowski told the Sun: “They [Prince Harry and Meghan Markle] have got to step out of that deep ghetto they’re in and recognise that everything they’ve done to date is going to be torn up, and they can start again.

The expert added that they could “rebuild themselves with authenticity”, saying: “If you haven’t got a team, haven’t got a central person who’s sense-checking you, you’re just gonna make the same mistakes all over again. It’s a definition of, sort of, lunacy, really.
