UK Jails Two Men for Illegally Gathering Intelligence for Hong Kong and Chinese Authorities
Two men, one a serving Border Force officer, have been handed substantial prison sentences in the United Kingdom after being found guilty of illegally gathering intelligence on pro-democracy campaigners residing in the UK. The intelligence operation, which benefited the Hong Kong and Chinese authorities, was uncovered and investigated by Counter Terrorism Policing, underscoring the serious nature of foreign interference on British soil.
Chi Leung Wai, also known as Peter, 41, from Staines-upon-Thames, received a total sentence of ten years’ imprisonment at the Old Bailey on June 18. His co-conspirator, Chung Biu Yuen, 66, of Hackney, was sentenced to eight years. Both individuals were convicted on May 7 of assisting a foreign intelligence service, an offence established under the National Security Act 2023.
Wai’s sentence comprised six years for the National Security Act offences and an additional four years, to be served consecutively, for misconduct in public office. This latter charge stemmed from his serious misuse of Home Office systems, which he accessed while employed as a Border Force officer. Detectives revealed that Wai exploited his privileged position to illicitly access the personal files of several Chinese and Hong Kong nationals living in the UK, compromising their privacy and security.
The head of Counter Terrorism Policing London, Commander Helen Flanagan, whose command led the intricate investigation, stated that the pair had been “targeting pro-democracy campaigners here in the UK” and sending “highly sensitive details about them and their families” to the Hong Kong authorities. Commander Flanagan emphasized that the convictions and sentences demonstrate “how seriously this kind” of activity “is taken in the UK and that it will not be tolerated.”
The investigation unveiled Yuen’s role in coordinating a network. As an office manager at the Hong Kong Economic and Trade Office (HKETO), Yuen was found to have been in contact with individuals linked to the Hong Kong authorities, receiving requests for intelligence. He then tasked Wai and others with conducting spying and surveillance focused on UK-based pro-democracy campaigners. Evidence presented during the trial included messages detailing Yuen making payments for these clandestine activities, despite his persistent denials of involvement.
The clandestine operation was disrupted following a police intervention on May 1, 2024. Counter Terrorism officers arrested nine individuals at a flat in Pontefract, West Yorkshire. The property belonged to a woman who had recently relocated to the UK from Hong Kong in 2023. She had been embroiled in a dispute with her former employer in Hong Kong, who had accused her of fraud – an accusation she denied, stating she had been set up. On the day of the arrests, a group including her former boss, Wai, and two former Hong Kong police officers, travelled to the flat. They allegedly posed as maintenance workers, poured water under her door, and then forcibly entered the premises. However, Counter Terrorism officers, who had been actively investigating the group, were already present and promptly made arrests as they entered.
A third man, Matthew Trickett, who had also been charged in connection with this case, was found dead in a park in Maidenhead on May 19, 2024, after being released on bail. An inquest into the circumstances of his death is anticipated to commence once the ongoing legal proceedings related to the intelligence gathering conclude.
Commander Flanagan described the investigation as “incredibly complex,” highlighting the immense scale of the evidence examined, which included more than 20 terabytes of data and thousands of messages spanning multiple languages. She further stated that the outcome should serve as a “stark warning” to anyone engaged in private investigation work to ensure their activities are not inadvertently, or deliberately, benefiting a foreign state. Commander Flanagan also expressed hope that the successful prosecution would offer reassurance to individuals residing in the UK who fear being targeted by foreign states, affirming that law enforcement is committed to taking decisive action to ensure their safety.
Why This Matters
The conviction and sentencing of Chi Leung Wai and Chung Biu Yuen mark a pivotal moment for the United Kingdom’s national security and its commitment to protecting democratic principles. This case is far more than a simple criminal prosecution; it illuminates the growing and complex threat of foreign interference on British soil, particularly from state actors seeking to suppress dissent and extend their influence beyond their borders.
Firstly, the involvement of a serving Border Force officer, Chi Leung Wai, represents a profound breach of public trust and a significant national security vulnerability. Wai’s exploitation of Home Office systems to access sensitive personal data of Chinese and Hong Kong nationals is a stark reminder of the insider threat. It demonstrates how foreign intelligence services can leverage individuals in positions of trust to gather information, compromising the safety and privacy of those who have sought refuge or made a home in the UK.
Secondly, the targeting of UK-based pro-democracy campaigners underscores a direct assault on fundamental democratic freedoms, including freedom of speech and assembly. The UK has historically been a sanctuary for political dissidents and activists. This operation reveals an effort by foreign powers to intimidate, surveil, and potentially silence critics, even when they are operating within the legal framework of another sovereign nation. Such actions can have a chilling effect on diaspora communities, leading to self-censorship and eroding trust in the state’s ability to protect its residents.
Thirdly, the case highlights the role and alleged misuse of diplomatic or quasi-diplomatic entities. Chung Biu Yuen’s position as an office manager at the Hong Kong Economic and Trade Office (HKETO) brings into question the scope and nature of activities conducted by such offices. While HKETOs officially promote economic and trade ties, their alleged involvement in intelligence gathering raises serious diplomatic concerns and may lead to increased scrutiny of their operations in host countries.
Fourthly, this prosecution is a crucial test and demonstration of the UK’s National Security Act 2023. Enacted to counter evolving threats from hostile states, the Act provides law enforcement with stronger tools to tackle espionage, sabotage, and foreign interference. The successful application of this legislation in such a high-profile case sends a clear message that the UK is prepared to use its new powers to robustly defend its interests and citizens against state-sponsored aggression.
Finally, the case carries significant geopolitical implications. It explicitly links the intelligence gathering to “Hong Kong and Chinese authorities,” reinforcing concerns about the erosion of Hong Kong’s autonomy and the increasing reach of Beijing’s security apparatus. For the international community, this serves as a potent illustration of China’s expanding global influence operations and the imperative for democratic nations to strengthen their defenses against such tactics. The UK’s firm response, reflected in these convictions and lengthy sentences, signals a resolve to protect its sovereignty and uphold the rule of law in the face of state-backed interference.
