Socialist Democracy (Portuguese: Democracia Socialista, DS) is a far-left[1] Trotskyist group in Brazil.
DS has been most prominent in the municipal government of Porto Alegre, where DS member Raul Pont was vice-mayor from 1992 to 1996 and mayor from 1996 to 2000, and the state government of Rio Grande do Sul.
DS members played a significant role in the elaboration of the Participatory Budget (though they had initially opposed its introduction) and also in the arrangements for the three World Social Forums held in Porto Alegre.
In recent years, the PT has become more moderate, especially after party leader Luiz Inácio Lula da Silva became President of Brazil in 2003.
This caused tension in the entire left wing of the PT, including in Socialist Democracy.
