Two men found guilty of spying on Hong Kong dissidents in UK for China-linked authorities

The verdict and charges

On Thursday, May 7, 2026, a jury at London’s Old Bailey convicted Chi Leung “Peter” Wai, 40, and Chung Biu “Bill” Yuen, 65, of assisting a foreign intelligence service under the National Security Act 2023, according to Counter Terrorism Policing and BBC News. Wai was additionally found guilty of misconduct in public office for misusing Home Office systems while employed in Border Force.

Both men were remanded in custody pending sentencing; police statements say the date will be confirmed. The same prosecution confirmed the jury could not agree on a separate foreign interference count related to forced entry into a West Yorkshire flat; the Crown did not seek a retrial on that charge, BBC reporting notes.

Who the defendants were

Wai worked as a Border Force officer at Heathrow from December 2020, giving him access to a large immigration database used to track arrivals and immigration history, BBC coverage states. He had earlier served in the Royal Navy, worked as a Metropolitan Police officer until 2019, and held volunteer roles with City of London Police, the same reporting recounts.

Yuen, a retired Hong Kong police officer who moved to the UK in 2015, was office manager at the Hong Kong Economic and Trade Office (HKETO) in London—normally a trade-promotion post that UK reporting describes as increasingly politicised after 2019 Hong Kong protests. Prosecutors portrayed Yuen as Wai’s handler from mid-2021, receiving tasking that benefited Hong Kong and Chinese authorities.

What prosecutors said they did

Counter Terrorism Policing alleges Yuen forwarded requests from Hong Kong to Wai, who then ran illicit checks on Home Office systems on individuals tied to the pro-democracy diaspora. Detectives cite payments from Yuen to Wai and a colleague despite Yuen’s denials of involvement, and report combing more than 20 terabytes of data across multilingual messages.

BBC trial coverage adds granular episodes: Wai allegedly searched systems on days off and sick leave, messaged contacts using dehumanising language about dissidents, and—alongside associates—mounted physical surveillance, including arranging for activists such as Nathan Law to be followed to the Oxford Union in 2023 when Hong Kong had placed HK$1 million bounties on some campaigners.

The Pontefract break-in that triggered arrests

On 1 May 2024, police arrested nine people at a Pontefract property after a group forced entry, Counter Terrorism Policing says. The target was a woman who had relocated from Hong Kong amid a fraud accusation she denies; Wai allegedly used database access to trace her and confirm occupancy using a bogus parcel delivery.

The official narrative describes ruses—fake maintenance notes, water poured under a door—before the break-in. MI5 reportedly audio-recorded the intrusion. Wai allegedly discarded a fake warrant card suggesting City of London Police rank when officers moved in. The jury’s failure to convict on foreign interference for those events leaves that specific label legally unsettled even as the espionage assistance counts stood.

Death of co-accused Matthew Trickett

Wai allegedly drew fellow Border Force officer Matthew Trickett, an ex-Royal Marine, into surveillance work. After charges were filed in May 2024, Trickett was found dead in Maidenhead’s Grenfell Park in what investigators treated as a suspected suicide, BBC and police summaries state. An inquest was expected after the criminal case concluded.

His death does not resolve factual questions about his intent or knowledge, but it removed a live defendant from the trial narrative and concentrated public attention on Wai and Yuen.

Political and diplomatic reactions

Security Minister Dan Jarvis called the conduct an “infringement of our sovereignty” that would “never be tolerated,” BBC reports. The piece adds that Chinese ambassador Zheng Zeguang would be summoned by the Foreign Office after the convictions—a signal of formal displeasure short of the full expulsion ladder.

These reactions situate the case inside UK–China tension over transnational repression, Hong Kong national security law spillover, and parliamentary concern for dissidents granted BN(O) or other UK status.

Why the National Security Act matters legally

The 2023 act created UK criminal hooks for foreign power conduct that older law addressed unevenly. Assisting a foreign intelligence service carries high maximum penalties; paired with misconduct in public office for Wai, the sentencing phase will test how English judges calibrate harm to national security against personal gain and duration.

Appeals may turn on direction or control by a foreign service, public office definitions, and jury instructions on foreign interference counts that failed.

Impact on Hong Kong activists in Britain

Targets named in open reporting—including Nathan Law, Finn Lau, and scrutiny of politicians such as Sir Iain Duncan Smith—illustrate a pattern feared by exiles: migration does not automatically end risk if host-state databases or community spaces are compromised.

Finn Lau told BBC he still did not feel safe from spying risk and described protective habits. Civil society groups are likely to renew calls for database access audits, whistleblower channels inside Home Office contractors, and clearer warnings to BN(O) holders about PRC-linked social engineering.

Most-cited factual anchors from current reporting

Verdict date: 7 May 2026, Old Bailey. Defendants: Wai, 40; Yuen, 65. Convictions: assisting a foreign intelligence service (both); misconduct in public office (Wai). Failed count: foreign interference (no retrial sought). Key arrest date: 1 May 2024, Pontefract. Trickett death: 19 May 2024, Maidenhead. Statute: National Security Act 2023.

Use court schedules and CPS releases for final sentence lengths once handed down.

What to watch next

Watch Old Bailey sentencing remarks for factual findings on state direction, database breach scale, and restitution. Watch FO–embassy messaging, possible sanctions or diplomatic persona non grata moves, and Hong Kong government statements on HKETO staffing.

Separately, watch civil claims from surveillance targets and employment tribunals touching Home Office vetting after Trickett’s death and inquest.

Bottom line

British courts have now convicted two men of running a China-linked espionage support operation aimed at Hong Kong dissidents resident in the UK, anchored in immigration database abuse and paid surveillance. The failed foreign-interference verdict on the Pontefract raid shows juries can split on new statutes even when core spying counts stick.

For policymakers, the case is a case-study in how trade missions, community networks, and overstretched internal controls can intersect—leaving activists and ministers alike asking whether laws alone can outpace transnational pressure.
