The Communist Party of Spain (Spanish: Partido Comunista de España; PCE) is a communist party in Spain. Since 1986, it has been part of the United Left coalition, which is currently part of the electoral alliance Sumar. Two of its politicians are ministers in the current government of Pedro Sánchez: Yolanda Díaz (Minister of Labour and Social Economy) and Sira Rego (Minister of Youth and Children).
The PCE was founded by 1921, after a split in the Spanish Socialist Workers' Party (Spanish: Partido Socialista Obrero Español; PSOE). The PCE was founded by those who opposed the social democratic wing of the PSOE, because the social democrat wing did not support the PSOE's integration in the Communist International founded by Vladimir Lenin two years prior.
