Two British Chinese nationals are on trial in London after prosecutors said they acted on behalf of the Chinese government as secret law-enforcement or intelligence agents in Britain.
According to the Associated Press, the defendants are Bill Yuen, 65, a former Hong Kong police officer, and Peter Wai, 38, a U.K. border official. Prosecutor Duncan Atkinson told London’s Central Criminal Court that the pair engaged in “shadow policing operations” on behalf of the Hong Kong Special Administrative Region and, by extension, the People’s Republic of China.
The allegations centre on surveillance and intelligence-gathering directed at members of the Hong Kong diaspora in the UK, especially pro-democracy supporters. Prosecutors said the two acted as if they were legitimate law enforcement while gathering information on people Hong Kong considered persons of interest.
Yuen worked for the Hong Kong Economic Trade Office in London, where prosecutors said his role went beyond office management. Wai worked for U.K. Border Force, was also a special City of London constable and ran a private security company. Prosecutors say he used police systems to gather information for a private-work cover that functioned as spying, and that he was paid from a trade-office account.
The AP report said phone messages showed the two discussed surveillance of former Hong Kong lawmaker Nathan Law. Their interest extended to members of Parliament and government employees, with Yuen in 2023 providing the names of prominent politicians, including Conservative lawmaker Iain Duncan Smith.
The prosecution alleges that the activity took place between December 2023 and May 2024 and included assisting a foreign intelligence service as well as trying to force entry into a home. Wai also faces a separate misconduct-in-public-office charge. Both men have pleaded not guilty.
The trial is significant because it places Hong Kong-related espionage allegations squarely inside the UK legal system, where questions of foreign interference, diaspora safety and public-sector trust are increasingly sensitive. The AP report suggests the alleged surveillance was not limited to one or two isolated targets but was part of a broader effort to monitor activists, politicians and other perceived critics of Hong Kong and China.
The case will now turn on what jurors make of the digital messages, workplace links and alleged surveillance activity described by prosecutors. For now, the key point is that the state has accused the defendants of acting as covert agents while living and working in Britain.
The case will also test how far UK prosecutors can turn messaging, workplace access and surveillance activity into a coherent espionage narrative before a jury. Because the defendants have pleaded not guilty, the trial is likely to focus heavily on intent, state direction and whether the information gathering crossed the line from suspicious contact into criminal assistance to a foreign power.
The case arrives at a moment when concerns about foreign interference and transnational repression are already sensitive in Britain. That makes the trial more than a narrow criminal proceeding; it is also a test of how seriously the state treats diaspora surveillance.
If prosecutors are able to connect the messages, workplace access and surveillance to a foreign state tasking structure, the case could become one of the more significant UK proceedings on transnational repression and foreign interference involving Hong Kong activists and British institutions.
