Prince Harry brutally branded 'black sheep' of the Royal Family

The former president's second son claimed Harry had done a "huge detriment" to the Royal Family after turning his back on the UK.

However, Eric said Harry should not have to worry about being deported if Donald Trump is re-elected on November 5 despite the Duke of Sussex facing allegations he may have lied about his drug use when he applied for his US visa.

He told The Mail: "Truthfully I don't give a damn about Prince Harry and I don't think this country does either.

"My father loved the Queen and I think the monarchy is an incredibly beautiful thing."

Eric said Harry let his family down when he quit the monarchy and moved to California with wife Meghan and son Archie in 2020.

He continued: "You look at this one black sheep who doesn't exactly know where he is, led by a wife that is pretty unpopular, both here and over where you are."

Eric claimed Harry appeared to "have gone off the deep end and it's sad to watch".

Returning to the Duke of Sussex's visa status, Eric said: "I don't give a damn if he did drugs. It means nothing.

"I can tell you that our father and our entire family have tremendous respect for the monarchy."

It comes as Harry is facing a fresh fight over his US visa application with an American think-tank demanding it be made public after he admitted taking drugs in his memoir, Spare.

The Heritage Foundation questioned why the Duke of Sussex was allowed into the US following his reference to taking cocaine, marijuana and psychedelic mushrooms in the book published last year.

The conservative Washington DC group brought a lawsuit against the Department for Homeland Security (DHS) after a Freedom of Information request was rejected.

The case was brought because visa applicants must by law declare whether they have taken drugs. Failure to do so can lead to deportation, and Heritage wanted the US Government to release the records to see what Harry said about drug usage.

Heritage last week submitted a new court filing as it tries to reopen the case as it was not allowed to see private submissions to the judge by the Biden administration.
