Workers' Left Front

The Workers' Left Front – Unity (Spanish: Frente de Izquierda y de Trabajadores – Unidad, FIT-U) is an electoral alliance of four Trotskyist parties in Argentina: the Workers' Party (PO), the Socialist Workers' Party (PTS), Socialist Left (IS), and the Workers' Socialist Movement (MST). Initially founded in 2011, the alliance added MST in 2019. After the 2023 Argentine general election, the FIT-U has five national deputies in the National Congress of Argentina: Nicolás del Caño (PTS), Christian Castillo (PTS), Myriam Bregman (PTS), Alejandro Vilca (PTS), and Romina Del Plá (PO). The predecessor of FIT-U was the Frente de Izquierda y los Trabajadores, Anticapitalista y Socialista, which consisted of the PTS, IS and New Movement for Socialism (NMAS). It stood in the 2009 legislative elections. Attempts to include the PO in this front broke down because the PO insisted on filling the first three positions on the lists with its own members.
