Party ideologies and European foreign policy. Examining the transnational foreign policy space

Abstract

ABSTRACT The heterogeneity of foreign policy preferences has hampered a more effective Common Foreign and Security Policy. We examine the dimensionality of the EU foreign policy space by analyzing foreign policy votes in the European Parliament (1999–2019). As it contains the EU’s full geographical and ideological diversity, it is an important laboratory for testing expectations about what predicts foreign policy positions. Party ideologies structure voting on foreign policy: party-political disagreements over the CFSP and military interventions matter more on foreign policy votes than others. The left-right dimension and the EU integration dimension still explain a considerable share of voting patterns, although they matter less on foreign policy votes than others.
