Prince Harry will find out the result of a Court of Appeal challenge over his UK security arrangements on Friday, according to court listings. Harry is challenging the dismissal of his High Court claim against the Home Office over the decision of the Executive Committee for the Protection of Royalty and Public Figures (Ravec) that he should receive a different degree of protection when in the country.

When Harry was in the UK in April, barristers for the duke told the Court of Appeal that he was "singled out" for "inferior treatment" and that his safety, security and life are "at stake". However, the Home Office, which is legally responsible for Ravec's decisions, opposes the appeal, with its lawyers telling the court that Ravec's decision was taken in a "unique set of circumstances" and that there was "no proper basis" for challenging it.

The ruling will take place at the Royal Courts of Justice in London at 2pm on May 2.

Ravec has delegated responsibility from the Home Office over the provision of protective security arrangements for members of the royal family and others, with involvement from the Metropolitan Police, the Cabinet Office and the royal household.

Last year, retired High Court judge Sir Peter Lane ruled that its decision to downgrade Harry's security was lawful.

But, Shaheed Fatima KC, for the duke, told the court that he and the Duchess of Sussex "felt forced to step back" from their roles as senior working royals as they felt they "were not being protected by the institution".

Harry attended both days of the hearing at the Royal Courts of Justice, and could be seen taking notes and talking with part of his legal team during the appeal.

Parts of the hearing were held in private, meaning the press and public could not be in court, to discuss confidential matters.

When in the UK, Prince Harry must follow specific protocols related to his security arrangements, especially since he is not a working royal.

While he is still considered a member of the Royal Family and receives security when visiting, the level of protection he receives is assessed on a case-by-case basis. He must give advance notice of his visits and the level of security is determined by the Executive Committee for the Protection of Royalty and Public Figures (RAVEC).

The couple no longer have an official UK residence, after being asked to vacate Frogmore Cottage, a Grade-II listed property on the Windsor estate.
