The Home Office said RAVEC had considered the "likely significant public upset" that would stem from something happening to Prince Harry and was aware of the "tragic death" of his mother, Princess Diana, who died in a car accident in 1997 after her vehicle was pursued by paparazzi.

Prince Harry has been subjected to unlawful, unfair and unjustifiable treatment by the British government over the decision to take away his police protection when he is in Britain, his lawyer told London's High Court on Tuesday.

Prince Harry's lawyers are to demand his taxpayer-funded protection is restored as they claim it was unfair to remove police help.

Prince Harry's lawyers say the impact on Britain of any successful attack on the young royal mean he should get full police protection when he visits.

Harry's High Court hearing started in London on Tuesday, with the Duke of Sussex taking legal action against the U.K. Home Office over a decision to downgrade his personal protective security after he stopped being a "working royal".

Asked about the allegation by the Royal’s lawyers in a court battle, police minister Chris Philp told LBC Radio: 'I don’t accept that.'
