Prince Harry has lost a bid to bring a second High Court challenge against the Home Office after being barred from paying for police protection when visiting the UK.
The Duke of Sussex was seeking the go-ahead to secure a judicial review.
He was unhappy at a decision that he should not be allowed to pay privately for his security when told he no longer qualified for its protection after leaving for America with wife Meghan Markle two years ago.
The Home Office decided that the royal would no longer be receiving personal Met security while in Britain, even if he covered the cost himself.
But the High Court have today ruled that the Prince could not also seek a judicial review over whether to let him pay for the specialist officers out of his own pocket.
Just after 10am this morning, Mr Justice Chamberlain delivered his ruling.
A judge at a hearing earlier this month was asked by Harry's legal team to allow the Duke to bring a case over decisions taken by the Home Office and the Executive Committee for the Protection of Royalty and Public Figures.
But the Home Office, opposing Harry's claim, said Ravec considered it was "not appropriate" for wealthy people to "buy" protective security.
It decided that "the public interest does not warrant" someone receiving the level of protection on a publicly funded basis.
A barrister for the Home Secretary previously told London's Royal Courts of Justice that the Duke's offer to pay for Met Police protection would set an 'unacceptable' precedent.
Robert Palmer KC told the court: "Officers are expected to place themselves in harm's way to protect the principal [Royal under protection] and in the public interest.
"It's different from ordinary policing, and can only be provided when the public interest requires it.
"It is inconsistent with those principles for a private individual to be able to pay for that security."
Last week, the Duke and Duchess of Sussex released a statement saying they and Meghan's mum Doria Ragland were involved in a "near catastrophic car chase" as they left an awards ceremony in New York City.
The incident happened after the pair left the Ziegfeld Theatre in midtown Manhattan where the former actress, 41, was honoured at the Women of Vision Awards.
In a statement, the prince's spokesperson said the "relentless pursuit" lasted more than two hours by half a dozen vehicles.
They added it resulted in near collisions with other drivers on the road, pedestrians and police officers.
The couple were said to be "extremely upset and shaken".
