UK politicians told Chinese government agent 'active' in Parliament

CNN's Bianca Nobilo talks with MP Mark Logan about the UK domestic spy agency warning that an "agent of the Chinese government" has been actively working to "subvert" the processes of Parliament, a senior British lawmaker said. Ian Duncan Smith, a former leader of the ruling Conservative Party, said the situation had been revealed by MI5, Britain's domestic counter-intelligence service, which had warned House Speaker Lindsay Hoyle.
