Left Movement (Catalan: Moviment d'Esquerres, MES) is a social-democratic, pro-independence political party in Catalonia. The party was founded in November 2014 from the merger of New Catalan Left (NECat) and Catalonia Movement (Moviment Catalunya), which had both been formed by dissident members of the Socialists' Party of Catalonia (PSC) who were dissatisfied with what they saw as the party's lack of support for the independence movement. Its founders included Marina Geli (Moviment Catalunya) and Ernest Maragall (NECat), but both have ever since left for other parties—Geli joined the Together for Catalonia alliance ahead of the 2017 Catalan regional election, whereas Maragall defected to Republican Left of Catalonia (ERC) in 2018.
