欧州議会議員選挙
Elections to the European Parliament were held in Poland on 13 June 2004. 20.87% of eligible citizens voted; of these, 97.33% of the votes cast were valid. The elections resulted in a heavy defeat for the governing Alliance of the Democratic Left and Labor Union parties, although the very low turnout makes a direct comparison with national election results difficult. As expected the most successful party was the Civic Platform. Second place was taken by the strongly anti-EU League of Polish Families.
