THE next stage of the public inquiry into the shocking actions of undercover officers who infiltrated hundreds of left-wing groups resumed today.

Opening statements were made on the activities of the now-disbanded Special Demonstration Squad (SDS) between 1983 and 1992.

Testimonies will be heard over the next weeks from those targeted including activists from the Campaign for Nuclear Disarmament (CND), London Greenpeace, Freedom Press, and the Socialist Workers Party.
