[email protected] This article argues that the entrance of the Lijst Pim Fortuyn in the Dutch Parliament after the May 2002 elections shows the relevance of the Schattschneider –Mair thesis of party system change. Fortuyn introduced a new line of conflict that restructured party competition in the Netherlands. The introduction of this new line of conflict has transformed the Dutch party system abruptly. The Dutch case differs from many other west European countries in which the rise of a successful radical right-wing populist party has changed the party system gradually. Comparative European Politics (2007) 5, 282–302. doi:10.1057/palgrave.cep.6110097 Keywords: multi dimensional political space; lines of conflict; party system change Introduction The 2002 Dutch parliamentary elections were one of the most volatile in the history of Western Europe (Mair, 2002). From 1998 to 2002, the governing Purple coalition commanded almost a two-third majority in the Dutch Lower House, but after the 2002 elections it was left with only one-third of the seats.
