Left of Catalonia–Democratic Electoral Front

Left of Catalonia–Electoral Democratic Front (Esquerra de Catalunya–Front Electoral Democràtic, EC–FED), often shortened as just Left of Catalonia (Esquerra de Catalunya), was a left-wing political platform in Catalonia, formed by Republican Left of Catalonia (ERC), the Party of Labour of Catalonia (PTC) and Catalan State (EC) to contest the 1977 Spanish general election. The alliance was formed to allow the three parties to run for election, as they had not been yet legalized at the time. The alliance ran lists in all four Catalan constituencies for the Congress of Deputies, whereas for the Spanish Senate it supported the Agreement of the Catalans coalition. Its referent at the Spanish level was the Democratic Left Front (FDI).

EC–FED obtained the 143,954 votes (4.72% of the total) and 1 seat for Barcelona, and was dissolved shortly after the election.
