LONDON (Bernama-PA Media/dpa): The businessman accused of being a Chinese spy was invited to Buckingham Palace by the Duke of York, reported German Press Agency (dpa).
The man -- who was banned from Britain by the government on national security grounds -- visited Buckingham Palace twice, and also entered St James's Palace and Windsor Castle at the invitation of Prince Andrew, The Times reported.
On Friday, the duke said he "ceased all contact" with the businessman accused of being a Chinese spy when concerns were first raised about him.
Andrew met the individual through "official channels" with "nothing of a sensitive nature ever discussed," a statement from his office said.
The businessman brought a case to the Special Immigration Appeals Commission (SIAC) after then-home secretary Suella Braverman said he should be excluded from the UK in March 2023.
Several newspapers have reported that the king has been briefed about his brother's links to the alleged spy.
Braverman has called for the man -- known only as H6 -- to lose his anonymity, the Telegraph has reported, as a "deterrent to others taking part in similar activities."
Judges were told that in a briefing for the home secretary in July 2023, officials claimed H6 had been in a position to generate relationships between prominent UK figures and senior Chinese officials "that could be leveraged for political interference purposes."
They also said H6 had downplayed his relationship with the Chinese state, which -- combined with his relationship with Andrew, 64 -- represented a threat to national security.
At a hearing in July, the specialist tribunal heard the businessman was told by an adviser to Andrew that he could act on the duke's behalf when dealing with potential investors in China, and that H6 had been invited to Andrew's birthday party in 2020.
A letter referencing the birthday party from the adviser, Dominic Hampshire, was discovered on H6's devices when he was stopped at a port in November 2021.
In a ruling on Thursday, Justice Bourne, Judge Stephen Smith and Sir Stewart Eldon, dismissed the challenge.
It comes after the royal family reportedly took further steps over the summer to distance themselves from the disgraced duke, with the king said to have axed his £1 million (US$1.3 million) annual "living allowance" and the security Charles had been privately funding for Andrew's home.
Professor Rana Mitter, ST Lee Professor of US-Asia Relations at the Harvard Kennedy School and an expert in Chinese politics, told BBC that part of Chinese spying strategy is to look for people who might be "influential over time" but are "in a bit of a doldrums."
He said the situation involving the duke of York and H6 is "not so much about spying in the sense of trying to find out secrets, it's about trying to influence."
"Getting to know the elites of countries like Britain is a useful task not for immediate knowledge but maybe for long term development of links in society. It seems that's what has been going on here," Mitter said.
"One of the things that quite often will happen is looking out for who may be influential over time, but perhaps is in a bit of a down spot, a bit of a doldrums.
"One of the best examples from a generation ago would have been President Richard Nixon, after he had to resign in disgrace over Watergate he was frequently invited to China." - Bernama-dpa
