How is contestation on European integration structured among national political parties? Are issues arising from European integration assimilated into existing dimensions of domestic contestation? We show that there is a strong relationship between the conventional left/right dimension and party positioning on European integration. However, the most powerful source of variation in party support is the new politics dimension, ranging from Green/alternative/libertarian to Traditional/authoritarian/nationalist.
