It remains unknown whether the father and son, whose relationship has been strained in recent years since Megxit, managed to meet during the brief window between their flights.

Harry is back for an appeal against a High Court ruling on his security protection.

The Duke has been taking legal action against the Home Office over a decision made by the Executive Committee for the Protection of Royalty and Public Figures in February 2020.

The dispute concerns the level of protection he should receive when in the country.

Harry has argued that his children, Prince Archie and Princess Lilibet, cannot “feel at home” or “safe” in the UK unless his police protection is fully restored.

The High Court previously heard that Harry’s “status” had changed as a result of no longer being a “full-time working member of the Royal Family”.

This change in status has been central to the security dispute that brought the Duke back to British soil.

The legal battle highlights the ongoing consequences of Prince Harry’s decision to step back from royal duties in 2020.

His current visit marks another chapter in the complex relationship between the Duke and the royal establishment.

Meanwhile, King Charles and Queen Camilla have arrived in Rome for a historic state visit aimed at strengthening Britain’s relationship with Italy.

The royal couple will also visit the city of Ravenna during their four-day diplomatic trip.

A planned visit to the Vatican has been cancelled as Pope Francis recovers from double pneumonia.

With Vatican events removed from the itinerary, remaining engagements in Rome have been spread over two days.

Additional elements have been added to some events to compensate for the schedule changes.
