Prince Harry has suffered a crushing defeat in his High Court battle with the Home Office.
The Duke of Sussex's was fighting a 2020 decision by the Executive Committee for the Protection of Royalty and Public Figures (Ravec) that he should receive a different degree of protection when in the UK.
The court found there had not been any unlawfulness in reaching the decision of February 28 2020 and that any departure from policy was justified.
The court has also found that there has been no unlawfulness on the part of Ravec in respect of its arrangements for Prince Harry's visits to the UK following the 2020 decision.
The Duke of Sussex confirmed earlier this month that he intends to regularly return to the UK.

Harry had been told the would no longer receive the “same degree” of protection when in the UK from 2020.
Today's decision means the level of Prince Harry's taxpayer-funded personal security will not change when he travels to the country in the future.
A spokesperson for the Home Office said: "We are pleased that the Court has found in favour of the Government’s position in this case, and we are carefully considering our next steps. It would be inappropriate to comment further.
