Name theft charge 
The eponymous socialist organization "Left Opposition" (one of the successors of the Organization of Marxists, mainly from its Trotskyist wing; its representatives create a new left party "Social Rukh") accused "representatives of the previous authorities (KPU), marginal Russophiles ("Kievan Rus") and Black Hundreds (PSPU), who parasitize on the left movement”, of stealing its name. According to the statement of its activist Nina Potarskaya, their organization is named after the leftists of the 20s with whom they associate themselves (leftists in the Central Rada and the Left Opposition in the VKP(b) opposing Stalinism).
