He added: “It was impossible to say that this reasoning was illogical or inappropriate, indeed it seemed sensible.”

Vos described Ravec’s decision as “understandable and perhaps predictable,” and continued: “From the Duke of Sussex’s point of view, I said that something may indeed have gone wrong, in that an unintended consequence of his decision to step back from royal duties and spend the majority of his time abroad has been that he has been provided with a more bespoke, and generally lesser, level of protection than when he was in the UK.

“That did not in itself give rise to a legal complaint.”

According to a report by The Telegraph last month, Harry said his “worst fears” were “confirmed” after secret evidence was presented during the appeal — most of it behind closed doors because it was considered “confidential evidence.”

After the hearing, Harry said: “People would be shocked by what’s being held back.”

He also mentioned that his “worst fears have been confirmed by the whole legal disclosure in this case and that’s really sad.”

The report also claimed that Harry believes King Charles could have stepped in to help restore his security. However, Buckingham Palace has denied this.

A palace source told The Guardian: “These are matters of security and government policy and, as usual, it would be inappropriate to comment or intervene on either.”
