What Partido Socialista does

Partido Socialista (PS) is a social-democratic political party in Portugal founded on 19 April 1973 by Mário Soares and co-founders including Salgueiro Maia, Francisco Sá Carneiro, and Francisco Miller. The party emerged during Portugal's pre-revolutionary period and became one of the principal political forces following the Carnation Revolution of 25 April 1974, governing Portugal multiple times since, most recently under Prime Minister António Costa from 2015 to 2024. As of mid-2025, leadership comprises José Luís Carneiro as Secretário-Geral (Secretary-General) and Carlos César as President, with the party operating as the main opposition to the AD government.

The party provides political representation, policy advocacy, and governance participation services to Portuguese citizens. Its operational infrastructure comprises national organs (Congresso Nacional, Comissão Nacional, Comissão Política Nacional, Secretariado Nacional), 18 district federations covering mainland Portugal plus the autonomous regions of Madeira and Azores, and affiliated organizations including Juventude Socialista (youth wing), Mulheres Socialistas (women's organization), and the Associação Nacional de Autarcas do PS. The parliamentary group operates at ps.parlamento.pt, and the official press organ Ação Socialista has been published since 30 November 1978.

The party's core digital products include the ps.pt website, the Militante member portal (militante.ps.pt), an online registration system (adesoes.ps.pt), an online donation platform, and an email newsletter service. Communication channels span WhatsApp, YouTube, Facebook, the Ação Socialista digital newspaper at acaosocialista.pt, and physical events such as congresses, federative congresses, and the Academia Socialista training program. The party is a member of the Party of European Socialists (PES), the Progressive Alliance of Socialists and Democrats (S&D) in the European Parliament, and the Socialist International. Revenue is generated through three regulated streams under the Lei de Financiamento dos Partidos Políticos e Campanhas Eleitorais: state subsidies (subvenções públicas), membership fees (quotizações), and individual donations capped at approximately €10,000 per person per year, with corporate donations prohibited by law.
