The Duke of Sussex - who lives in California - was said to have been reconsidering plans for wife Meghan, Duchess of Sussex, and their children Prince Archie, seven, and five-year-old Princess Lilibet to join him in his homeland, where he has five days of events and engagements planned, after being denied police protection.
But a spokesperson for Harry has stressed the planned visit still remains on track, with the prince's father, King Charles, offering accommodation at a royal residence for part of the trip.
"Prince Harry's program in the United Kingdom includes both public and private engagements across the country. Safe accommodation is only one element of an effective protective security plan because risk follows the person, not the place," the representative told People magazine.
"The issue has never been accommodation. The issue is whether appropriate and proportionate protective security is being provided throughout the entirety of the visit.Â
"The independent Risk Management Board that RAVEC itself decided was necessary last November has still not taken place. It is therefore difficult to understand how the proportionality of the current arrangements can credibly be maintained without that independent assessment.
"The Duke continues to explore every available option to enable the visit to proceed safely and to give his children the opportunity to enjoy the UK."
According to The Telegraph, Harry had been told his application for a security package for the visit has been denied and an insider blasted the Home Office and the committee responsible for assessing their security of "wilfully creating conditions that are making it nearly impossible" for them to honour their commitments in Britain as they will only receive taxpayer-funded security when they are within royal residences.
"The precarious security situation and endless speculation about where the family will stay is making the planning and logistics for the private security team increasingly difficult," a source close to the Sussexes told The Telegraph.
"The Home Office and the Ravec board are wilfully creating conditions that are making it nearly impossible to move the family from A to B.
"There have been three separate incidents in the UK in less than 12 months that we know of, each involving a fixated person getting to within feet of the Duke.
"In some circumstances, because of the limitations on what private security have the authority to do, they weren't able to remove the person," the source said.
The prince is said to be "desperate" for his children to see their grandfather, as he last saw them in 2022 when the family flew to the UK for the late Queen Elizabeth's Platinum Jubilee celebrations.
"The UK government's protective security system is rigorous and proportionate," a government spokesperson said.
"It is our long-standing policy not to provide detailed information on those arrangements, as doing so could compromise their integrity and affect individuals' security."
