On June 18, 2026, a UK court sentenced Peter Wai, 41, and Bill Yuen, 66, for spying on Hong Kong pro-democracy activists living in the UK. Wai, a former UK Border Force officer, received a 10-year sentence, while Yuen, a retired Hong Kong police superintendent, was sentenced to eight years. Both were convicted under the UK's National Security Act for assisting a foreign intelligence service, marking the first known espionage convictions in the UK linked to China targeting Hong Kong dissidents.
Wai was additionally found guilty of misconduct in public office after unlawfully accessing UK government databases to gather information on activists and British politicians critical of China. Targets of surveillance included former Hong Kong lawmaker Nathan Law and UK officials vocal against Beijing policies.
In the courtroom, Judge Bobbie Cheema-Grubb emphasized that modern foreign intelligence goes beyond traditional espionage, involving surveillance, intimidation, and targeting dissidents sheltering under UK laws. Commander Helen Flanagan of Counter Terrorism Policing London described the activities as "truly chilling."
The Chinese embassy in London dismissed the charges as politically motivated and denied any official role. However, the UK Foreign Office responded by summoning the Chinese ambassador, intensifying diplomatic tensions over national security and treatment of Hong Kong activists.
Surveillance activities occurred from December 2023 to May 2024 amid concerns about foreign interference in UK territory. The case underscores growing legal and diplomatic challenges surrounding espionage law and civil liberties.
By the numbers:
- 10 years — Peter Wai's prison sentence
- 8 years — Bill Yuen's prison sentence
- December 2023 to May 2024 — period of surveillance activities
