The Anticapitalist Left Cooperation for the Overthrow, better known domestically by the acronym ΑΝΤ.ΑΡ.ΣΥ.Α., is a coalition of radical-left political organisations in Greece.

The Workers Revolutionary Party is a Trotskyist communist political party in Greece, taking part in the elections independently, since the departure from Radical Left Front coalition in spring of 2009. EEK does some cooperative work with the Front of the Greek Anticapitalist Left (ANTARSYA), which the rest of MERA joined in 2009.
