Prince Harry is seeking a judicial review against the refusal of the Home Office to allow him to personally pay for police protection when in the UK.
US-based Prince Harry says he and his family are “unable to return to his home” as it is too dangerous for them.
A government spokesperson said the UK’s “protective security system is rigorous and proportionate”.
They added: “It is our long-standing policy not to provide detailed information on those arrangements. To do so could compromise their integrity and affect individuals’ security.”
The Duke and Duchess of Sussex lost their taxpayer-funded police protection when they stood down as senior working royals in March 2020.
The legal challenge follows a security incident in London last summer when Prince Harry’s car was chased by photographers as he left a charity event.
A representative for Prince Harry said he wants to personally fund police protection, “not to impose on the taxpayer”.
A statement said: “Prince Harry inherited a security risk at birth, for life.
“He remains sixth in line to the throne, served two tours of combat duty in Afghanistan, and in recent years his family has been subjected to well-documented neo-Nazi and extremist threats.”
The duke, who is now based in California, is arguing that his private security team cannot replicate the work of police protection in the UK, with access to local intelligence and legal jurisdiction.
His legal representative said he offered to pay the costs of police protection in January 2020 at Sandringham, when talks with the Queen were being held over the Sussexes’ future role. But the offer was dismissed, the representative said.
“The UK will always be Prince Harry’s home and a country he wants his wife and children to be safe in. With the lack of police protection, comes too great a personal risk,” the statement said.
The Sussexes’ daughter, Lilibet, is now seven months old and has yet to meet her great-grandmother the Queen, grandfather the Prince of Wales and other members of the family.
The couple were forced to disclose they had put in place “privately funded security arrangements” for their move to the US, after then-president Donald Trump said the country would not pay for their protection.
