Socialist Unity (Spain)

Socialist Unity (Spanish: Unidad Socialista, US) was a Spanish party alliance formed to contest the 1977 general election by the People's Socialist Party (PSP) of Enrique Tierno Galván and the Federation of Socialist Parties (FPS).

[1][2] In the Senate, this party only contested some of the constituencies, as the PSP participated in other left-wing coalitions along the Spanish Socialist Workers' Party (PSOE).

Of those, five were from the PSP (three from Madrid, including Tierno Galván, and the rest from Cádiz and Valencia each one) and one of the Socialist Party of Aragon (PSAr), from Zaragoza.

Given the small number of deputies, the six Unidad Socialista representatives in Congress were placed in the Mixed Group.

[3] After the PSP and most of the parties within the FPS merged with PSOE throughout 1978, the majority of US deputies and senators were absorbed into PSOE's parliamentary groups in the Congress and Senate.
