The prince said yesterday that he will 'explore all options' for his upcoming trip to be safe

Prince Harry and Meghan Markle are to blame for their "chaotic" security situation, a royal commentator has claimed.

The Sussexes publicly announced last week that they were returning to the UK – for some, namely Meghan, Archie, and Lilibet, it marks their first appearance on British soil for four years.

However, Harry's security problem continues to linger. The trip was cast into doubt over the weekend when it was revealed that the Executive Committee for the Protection of Royalty and Public Figures (Ravec) had "paused" the independent Risk Management Board (RMB) without explanation.

The duke's office is said to have been informed that this would have been completed in March.

In response, Harry's spokesman said that he "continues to explore every available option to enable the visit to proceed safely and to give his children the opportunity to enjoy the UK".

Royal commentator Richard Fitzwilliams suggested that the delay to Ravec's decision could be sensitivity over the costs to the taxpayer.

He said the "situation is chaotic" – but the Sussexes have no one but themselves to blame.

"On the one hand, it is very curious indeed that the assessment by Ravec, which was promised last December after he lobbied the Home Secretary, has not taken place," he told The People's Channel.

"This has always been a red line for him after the tragic death of his mother."

He added: "The fault here is that the Sussexes have planned this so publicly – the rift is deep."

The King is said to have offered royal accommodation for the family to stay in, though Harry has not responded yet.

It is understood the property would be covered by security, but nothing else would be.

Harry would instead be protected solely with a phone number for a police liaison officer and his own private bodyguards, who are legally banned from carrying firearms and do not have access to police or secret intelligence.

Harry's spokesman made clear that accommodation is not the central concern. He said "the issue has never been accommodation", adding that "appropriate and proportionate" security throughout the entirety of the visit was the priority.

Mr Fitzwilliams stated that the couple "are not trusted by the Royal Family," adding: "However, they are two of the most high-profile people in the world, and there have been threats, and Harry has a female stalker."

Despite the concerns, the Sussexes are "desperate for this trip to go ahead," he declared.

A proposed meeting with the King and a trip to Harry's mother, Princess Diana, who was laid to rest on the Althorp Estate, her family's ancestral Northamptonshire property, is "very important".

It has been suggested that Harry could fly out Meghan and his two children just for the day in a last-ditch attempt to navigate his tricky security concerns.

The family is currently holidaying in Europe ahead of their scheduled trip.
