Leadership Dynamics in European Union Governance

Leadership in the European Union is characterised by a complex interplay between intergovernmental and supranational actors, formal office-holders and informal coalitions. Since the Lisbon Treaty, the distribution of authority has shifted, elevating figures such as the President of the European Council and the High Representative for Foreign Affairs alongside the rotating presidency of the Council of the EU. This plurality of leadership roles has reshaped agenda-setting, negotiation dynamics and crisis response, whether in economic governance, enlargement policy or external affairs. While institutional design provides the legal framework, evolving norms of impartiality, identity and trust among member-state representatives exert a decisive influence on the ability of chairs and presidencies to broker compromises. Bureaucratic services, notably the European External Action Service, and collaborative groupings of presidencies also contribute to continuity and strategic coherence. Together, these factors underpin both the agility and the tensions of EU decision-making, with far-reaching implications for global governance and the Union’s capacity to act in an increasingly multipolar world.
