Some were useful idiots; some were Soviet agents

There was a popular belief amongst conservatives when I was growing up that the anti-War/anti-nuclear movement wasn’t simply a spontaneous awakening amongst the citizenry, alarmed by the direction their countries were taking, but was instead a concerted effort by Communist agents planted in the West.  That apparently paranoid conservative suspicion of the 1960s and 1970s (dead and politically incorrect by the 1980s) now proves to be true in at least one case coming out of Great Britain:

Labour was rocked by a Cold War spy scandal last night over allegations that a Party activist linked to two members of Tony Blair’s Cabinet spied for the Czech Government when the country was controlled by the Soviet Union.

Left-wing activist Cynthia Roberts, who stood as a Labour Parliamentary candidate, worked for the Communists under the codename Agent Hammer, according to documents obtained by The Mail on Sunday.

Mrs Roberts moved to the Czech capital from London, where she used a House of Commons office to run the controversial Labour Action for Peace (LAP) group, which opposed nuclear weapons, and had links to Soviet Moscow.

The disclosures are a reminder of how close some elements of the Labour Party were to the Soviet Union before the fall of communism 20 years ago.

Even paranoid people and countries have enemies.
