LONDON: UK police said Saturday they had arrested a man in his twenties for spying, with the Sunday Times reporting he was a researcher in Britain’s parliament suspected of working for China. “Officers from the Metropolitan Police Service arrested two men on 13 March on suspicion of offenses under section 1 of the Official Secrets Act, 1911,” said the force. “A man in his 30s was arrested at an address in Oxfordshire and a man in his 20s was arrested at an address in Edinburgh.” The Sunday Times said the suspect in his twenties had contacts with MPs from the ruling Conservative Party while working as a parliamentary researcher. They included Security Minister Tom Tugendhat and Alicia Kearns, the chairman of the Commons foreign affairs committee. He is a Briton who has worked on international policy, including relations with Beijing, and previously worked in China, the paper added. If proven, it would represent one of the most serious breaches of security involving a hostile state at the UK’s parliament. Domestic intelligence service MI5 last year warned that a female Chinese government agent called Christine Lee had been “engaged in political interference activities on behalf of the Chinese Communist Party, engaging with members here at parliament.” In July the Commons intelligence and security committee claimed that China was targeting the UK “prolifically and aggressively” and that the government did not have the “resources, expertise or knowledge” to deal with it. Tugendhat is reported to have only had limited contact with the suspect, and none while security minister.
