MOSCOW (Sputnik) – The former undercover officers worked in the Special Demonstration Squad (SDS), a special undercover unit of the Metropolitan Police Service (Met) that spied on at least 460 political groups in 1968 – 2008.
In one of the documents seen by The Guardian police said that there were a number of reasons for strained relations between the officers and the Met.
According to another document, the Met said that some of the undercover officers "assert that they have suffered psychiatric damage as a consequence of their deployments."
Police said that at least 150 officers worked undercover or supervised undercover colleagues since 1968.
The investigation of conducting undercover operations led by Lord Justice of Appeal Christopher Pitchford was established by incumbent UK Prime Minister Theresa May when she was Home Secretary.
