Using data from the Comparative Manifestos Project, we compare the policy positions of left and right parties with regard to immigration across 18 West European countries between 1975 and 2005. We test two main hypotheses: First, we expect that mainstream parties will exploit anti-immigrant sentiments in the electorate regardless of extreme right competition. This would indicate that the extreme Right is not the only driving force behind the recent ‘anti-immigrant turn’ of electoral politics in Western Europe. Second, we expect the mainstream Left to become increasingly critical towards immigration as its mainstream and/or extreme right competitors intensify their populist rhetoric. Being ‘tough’ on immigration is thus not a prerogative of the Right. We conclude that the impact of the extreme Right on the electoral behaviour of mainstream right parties has been overstated in previous studies
