Prince Harry is longing to spend more time in the UK with the Royal Family but there is one unanswered question that’s stopping him, an insider has claimed.

The Duke of Sussex has been locked in discussions over whether to return to his home country next month to attend the Invictus Games 10th Anniversary Service at St. Paul’s Cathedral in London on May 8.

But the latest developments regarding his security in the country have left the prince considering appearing digitally, via video link or a pre-recorded message.

Harry’s predicament comes after he lost a bid to appeal his case against the Home Office over police protection, leaving him without the automatic right to use the royal security services.

The Government’s stance is that his security, when in Britain, should be self-funded, except during official royal events or when accompanying the royal family.

And while the duke may wish to spend more time with his father, King Charles, who is currently undergoing treatment for cancer, it seems the only way to do so would centre around his level of security while in the country.

A source close to the prince explained: “Harry wants to spend more time in the UK with his family.

“But there’s no way he can do that while a question mark hangs over his security detail.”

They added that the royal has been left “disappointed” by the decisions made regarding his security, saying: “His request for security was not just for his personal safety but also for his family, the public and the officers assigned to him”.

Harry’s security claim was dismissed back in February, while court documents released last week revealed that his application to appeal the ruling was also rejected by the judge, as was his request to pay just 40 percent of the government’s costs, which exceeded £500,000.

The judge ordered him instead to pay 90 percent which means that Harry now faces an estimated cost of £1 million, including his own legal fees.

High Court judge Sir Peter Lane found that “there has not been any unlawfulness in reaching the decision” to revise his security, adding: “Any departure from the policy was justified. The decision was not irrational. The decision was not marred by procedural unfairness.”

Despite the setback, the source stated that Prince Harry remains committed to the Invictus Games and its participants.
