Agnes Batory and Uwe Puetter, both faculty members of the DPP and member and director, respectively, of CEUR, published an article in the Journal of European Public Policy on one of the most important drivers of European integration, the Presidency of the European Council. The Lisbon Treaty introduced significant changes to the Presidency, which now combines a permanent chair with the principle of rotation based on three member states collaborating during an 18-month period. By discussing the joint Presidency of Spain, Belgium and Hungary, the article interprets this model as an attempt to re-adjust the balance between consistency and diversity in EU policy making. Rotation remains a key instrument for ensuring the representation of the diversity of member states in an enlarged Union. At the same time, the EU's ever more complex policy agenda and a greater need for collective leadership motivate the search for new forms of co-operation to enhance policy consistency over consecutive Presidency terms.
