Prince Harry has responded to  the Court of Appeal's decision to reject his challenge to the High Court's decision of his UK security arrangements.

Sitting down with the BBC's Nada Tawfik near his home in Santa Barbara, California, the Duke denounced the ruling.

The King’s youngest son, 40, sought to challenge the original decision by High Court judge Sir Peter Lane in February last year, which determined that the Executive Committee for the Protection of Royalty and Public Figures (Ravec) was right to remove his high-level police protection while he's in the UK.

But in a ruling on Friday, Sir Geoffrey Vos, Lord Justice Bean and Lord Justice Edis dismissed Harry's appeal.

Sir Geoffrey Vos summarised the decision and told the court that while the Duke of Sussex's personal arguments were both "powerful and moving", he concluded that: "I could not say that the Duke's sense of grievance translated into a legal argument for the challenge to Ravec's decision."

He said: "The duke was in effect stepping in and out of the cohort of protection provided by Ravec.

"Outside the UK, he was outside the cohort, but when in the UK, his security would be considered as appropriate."

Prince Harry said: "The only thing I've been asking for in this whole process is safety."

He continued: "I can only come to the UK safely if I'm invited. There is a lot of control and ability in my father's hands. Ultimately this whole thing could be resolved through him, not necessarily by intervening but by stepping aside and letting the experts do what is necessary."

The duke also said that he was cut off from his father who he said "won't speak" to him because of "this security stuff".

Harry told the BBC: "I can't see a world in which I would bring my wife and children back to the UK at this point and the things that they're going to miss is, well, everything. I think it's really quite sad that I won't be able to show my children my homeland."

When asked if he felt let down by the UK, Harry said he felt "very let down" at this point.

Harry also said the security case has been a "sticking point" for the rifts between himself and his family. He told the BBC: "Of course, some members of my family will never forgive me for writing a book, of course they will never forgive me for lots of things, but I would love reconcilation with my family."
