Threat to UK from hostile states could be as bad as terrorism, says MI5 chief

Ken McCallum says public should be alert to threat from China and Russia

The chief of MI5 is to warn that the activities of China, Russia and other hostile states could have as large an impact on the public as terrorism, marking a significant shift in emphasis from the UK's domestic spy agency.

Giving his annual threat update on Wednesday, Ken McCallum is expected to say that the British public will have to build the same public awareness and resilience to state threats that we have done over the years on terrorism".
