Dimensionality, ideology and party positions towards European integration

This article extends the existing approaches in two important ways. First, it shows that whether the dimensionality of politics is imagined in a one-dimensional ‘general left‒right’ form or a two-dimensional ‘economic left‒right/social liberal-conservative’ form leads to very different understandings of the way ideology has structured attitudes towards European integration, with the two-dimensional approach offering greater explanatory power.

Second, existing approaches have modelled the influence of ideology on attitudes towards European integration as a static process. This article shows that the relationship between ideology and European integration has changed substantially over the history of European integration: divisions over social issues have replaced economic concerns as the main driver of party attitudes towards European integration.
