UK’s MI5 Chief Expresses Frustration Over Collapse of China Spy Case

Security officials say the failed prosecution has strained intelligence efforts.

The head of MI5 has voiced frustration following the collapse of a major espionage case involving two men accused of spying for China.

The case was dropped after prosecutors said key evidence could not be disclosed in court for national security reasons.

Officials warn the outcome could hinder future counterintelligence operations and expose gaps in how sensitive information is handled in espionage trials.
