This is a summary – from the August 1968 monthly political report from the Indian High Commission in Colombo – of disagreements within the Sri Lankan left over the Soviet intervention in Czechoslovakia in 1968. I had to google “Keuneman revisionist clique” – apparently it was what the pro-Moscow, electorally-inclined faction of the Communist Party of Sri Lanka was called by its left critics. For a really deep dive, this 1974 book by an “anti-revisionist” Sri Lankan Marxist regularly uses the term, while also highlighting “the Marxist-Leninist Communist Party alone warned against placing faith in the fraud of bourgeois parliamentary democracy” and lamenting how “Khrushchov [sic] usurped power by means of a palace revolution and embarked on the treacherous course of modern revisionism, abandoning the revolutionary principles of Marxism-Leninism.”
