The Miners’ Union leader was definitely a KGB asset. Can’t think of his name right now but he was the “in the streets” protests leader.
Suspect that Peggy Duff, a leader of the anti-defense lobby in England, was also KGB in the 60’s possibly through the 80’s if she was still around for the Soviet funded Campaign for Nuclear Disarmament (CND). They showed up at US air bases and nuclear sub bases, as well as protested the cruise and Pershing missile deployments in the 1980’s. James Lamond another possible KGB asset, Lord Mayor of Aberdeen, Labor party 1977-80 period.
Nicholas Schoten of the Dutch disarmament movement leadership was caught receiving Soviet money for the protests.
The KGB had infiltrated every major opposition movement in the major NATO countries of Europe, and often had their “assets” become the leaders of them (England, France, Belgium?, Netherlands, Sweden (Bertil Vennsthrom? and/or Harald Edelstem - diplomat, Ambassdor to Algeria).
England was probably the most infiltrated country besides West Germany (Brandt’s secretary was a KGB agent, as was another high-ranking member of either his or the Schmidt government).
Never underestimate the infiltration/subversion power of the old Soviet Union, its’ child, Putin’s Russia, and esp. the Red Chinese regime in Peking which is making inroads into Africa and Asia that the Russians could only dream about.
