The Duke of Sussex has lost his High Court battle over changes to his personal security in the UK.

Prince Harry took legal action against the Home Office after a decision was made by the Executive Committee for the Protection of Royalty and Public Figures (Ravec) to no longer give him the “same degree” of publicly-funded protection when in the country as other royals.

At a hearing in December last year in London, Harry's lawyers said he was "singled out" and treated "less favourably" by Ravec, who are given responsibility from the Home Office over the royal family's security arrangements.

His lawyers argued that there was an inadequate risk analysis done which made their approach to his protection "unlawful and unfair".

However, the government argued that Harry's claim should be dismissed as Ravec was entitled to conclude that the duke's protection should be evaluated on a "case-by-case" basis.

In a hearing today, retired High Court judge Sir Peter Lane rejected the duke's case against the Home Office and Ravec.

Since moving to America with his wife Meghan Markle and their two children, Prince Harry has returned to the UK only a handful of times, most recently to see his ill father King Charles III.

He flew from California to see the King for just 45 minutes days after his father's cancer diagnosis was announced.
