cpi(ml) unity organisation had launched a mass organisation, the mazdoor kisan sangram samiti ('worker-peasant struggle association'), together with dr. vinayan (an ex-socialist mass leader). cpi(ml) party unity effectively functioned as the armed wing of mkss. cpi(ml) party unity managed to get the bhoomi sena (a kurmi caste paramilitary outfit) to formally surrender to mkss. in 1986 mkss was banned. eventually there was a rupture between dr. vinayan and the party, and dr. vinayan's mkss faction denounced the party in 1987. cpi(ml) party unity launched the mazdoor kisan sangram parishad as its new peasant front.
