欧州議会議員選挙
Elections to the European Parliament were held in the 27 member states of the European Union (EU) between 4 and 7 June 2009. A total of 736 Members of the European Parliament (MEPs) were elected to represent some 500 million Europeans, making these the biggest trans-national elections in history. An additional 18 observers ("virtual MEPs") were (supposed to be) pre-elected.
