This article takes stock of the fragmented scholarship on parliamentary approaches to the study of European foreign policy. Parliamentary studies on European foreign policy are not only being located at different levels of analysis (the national, the inter-parliamentary, the European and the global), they also tend to focus on different actors (national parliaments, inter-parliamentary networks, the European Parliament and other IPIs) and different processes (parliamentarisation, parliamentary cooperation or parliamentary diplomacy). In order to overcome fragmentation of the field of study and to bridge, his article makes the suggestion of applying a transnational perspective (Hurrelmann/DeBardeleben 2011; Risse-Kappen 1995; Keohane/Nye 1974) to provide a more all-encompassing approach to study of the parliamentary dimension of European Foreign Policy. The paper also critically reflects how such an approach differs from existing approaches to European Foreign Policy, and if it has any added-value to the study.
