In the past, European election campaigns have been fought primarily at national level, organized and led by national parties. The European political parties had neither the financial nor the organizational means to lead pan-European election campaigns. The June 2009 elections, however, highlighted a different and potentially significant trend: new EU regulations provided for the direct financing of European political parties, allowing them to campaign directly in the elections. It is argued that these developments could lead to the Europeanization of European elections campaigns. This article applies the concept of Europeanization to the election campaigns of the Party of European Socialists and three of its member parties: the British Labour Party, the French Socialist Party and the German Social Democrats, creating an ideal-type model of Europeanization. It concludes that in the three cases Europeanization is still in its infancy.
