Prince Harry, Meghan Markle have reportedly come under siege after new shocking revelations during ongoing investigation.
According to a royal expert, the Duke and Duchess of Sussex could also be under threat after FBI's report that the man, who tried to assassinate Donald Trump, also researched Kate Middleton.
Jenni Bond told OK!: "Security threats are a fact of life for the Royal family and Prince Harry is an even more obvious target because of his military record."
"His concerns about security for himself and his family are legitimate and the bill they face for their private protection in the States must be enormous. But that is something they must have understood when they decided to leave royal life and the UK."
Bond went on saying that there have been "countless occasions" when "people have scaled the walls around Buckingham Palace" or even got into the Palace, including the Queen’s bedroom.
"It obviously means that they have to earn a lot of money, but they are not alone in facing these security threats. Countless A-list celebrities have to employ bodyguards – such is the sad state of society these days."
It's also noteworthy that Prince Harry suffered a loss in his ongoing legal battle this year over police protection in the UK, after his initial bid to appeal a High Court ruling was rejected.
