A UK immigration officer has been found guilty of working for Chinese intelligence as part of a "shadow policing operation".
Chi Leung "Peter" Wai, 40, used his access to the Home Office computer system to track Hong Kong dissidents based in the UK through the main immigration database.
He was found guilty under the National Security Act of assisting a foreign intelligence service alongside Chung Biu "Bill" Yuen, 65, who was initially his contact with the Hong Kong authorities. Wai was also found guilty of misconduct in public office.
Chinese ambassador Zheng Zeguang will be summoned by the Foreign Office after the two men were found guilty.
Security Minister Dan Jarvis said the men's activities were "an infringement of our sovereignty and will never be tolerated".
