PES in the European institutions -- Overview of the European institutions
The Party of European Socialists (PES) is a social-democratic European political party. The PES comprises national-level political parties from all member states of the European Union (EU) plus Norway and the United Kingdom. This includes major parties such as the Italian Democratic Party, the British Labour Party, the French Socialist Party, Social Democratic Party of Germany and the Spanish Socialist Workers' Party. Parties from a number of other European countries are also admitted to the PES as associate or observer parties. Most member, associate and observer parties are members of the wider Progressive Alliance or Socialist International. The PES is currently led by its president Sergei Stanishev, a former Prime Minister of Bulgaria. Its political group in the European Parliament is the Progressive Alliance of Socialists and Democrats (S&D). The PES also operates in the Committee of the Regions (in the PES Group in the Committee of the Regions) and the European Council.
