A notice issued by the Undercover Policing Inquiry said that William Paul Lewis, known simply as “Bill”, “may have been encountered by
individuals involved with the International Marxist Group or the Vietnam Solidarity Campaign.”
He was deployed between 1968 and 1969, the inquiry said — which would mean he was one of the first officers in the Metropolitan Police’s Special Demonstration Squad.
This elite unit was set up to gather long-term intelligence on protest groups following demos against the Vietnam war.
The public inquiry into undercover policing was set up two years ago following revelations of officers’ activities — including the deception of women activists into relationships.
It has still not held any evidence hearings and is unlikely to do so until the second half of 2019.
