What Do the Leaked Messages in the UK China Spy Case Show?

A British man acquitted of spying for China told the BBC he was a "convenient fall guy" for police and security services seeking to publicize foreign espionage threats, while acknowledging he was "unprofessional and naive." Chris Cash, a former parliamentary researcher, made the comments in his first interview since his acquittal, in a report by BBC News.

What did Chris Cash say happened to him?

Cash said counter-terror officers entered his bedroom and arrested him, according to the BBC. He said he would "never do anything" to harm UK national security, but conceded he sent "gossiping" texts to a friend in China that he now views as unprofessional.

What do the newly disclosed messages show?

Cash shared more than 6,000 messages with the BBC documenting communication with Chris Berry, a friend he met in 2018 while the two taught English in China. The messages show Berry describing a "secret" meeting with a high-ranking Chinese official, who reportedly raised concern about a sanctioned British MP potentially being promoted to a cabinet role. The messages also show Cash listing Berry as a reference during vetting for his parliamentary pass, which was approved, the BBC reported. The outlet found no evidence in the trove that Cash was paid by, or sympathetic to, the Chinese Communist Party.

What happened to the criminal case against Cash and Berry?

Both men were charged with espionage and both maintained their innocence throughout, according to the BBC. Cash was acquitted, a result that "sparked a political row over the government's failure to designate China as a 'threat,'" the outlet reported. Berry declined to comment on the BBC's latest reporting but said at the time of his own acquittal that he had been "unfairly subjected to a trial by media." Berry said he supplied reports to a Chinese company he believed served clients seeking UK trade links, and that the reports contained no classified information and relied on public sources.

What is the timeline of the case?

• 2018 — Cash and Berry meet while teaching English in China.
• 2019 — Cash returns to the UK, later becoming director of a small policy group run by China-skeptic Conservative MPs in Westminster; Berry remains in China, writing reports for a large consultancy with government links.
• 2022 — Messages reference the Conservative Party leadership contest and a Chinese official's concern about a sanctioned MP's possible cabinet promotion.
• Unspecified later date — Both men are charged with espionage.
• Acquittal — Both men are cleared; Cash gives his first interview since, telling the BBC he believes his prosecution was meant as a warning to others.

What remains unresolved?

UK security services alleged that information from the men's messages, sent on encrypted channels, was relevant to their case, the BBC reported. The outlet's review did not establish payment or ideological sympathy on Cash's part, and Berry has disputed the characterization of his work. The government's broader stance on designating China a national-security "threat" remains disputed following the acquittals, according to the report.
