The European Union is a key player in determining policies and politics in Europe, and yet understanding how it works remains a challenge. The Politics of the European Union introduces students to its functioning by showing the similarities and differences between the EU and national political systems. Fully revised and updated in its third edition, this introductory textbook uses the tools of comparative politics to explore the history, theories, institutions, key actors, politics and policy-making of the EU. This comparative approach enables students to apply their knowledge of domestic politics and broader debates in political science to better understand the EU. Numerous real-world examples guide students through the textbook, and chapter briefings, fact files and controversy boxes highlight the important and controversial issues in EU politics. A companion website features free 'Navigating the EU' exercises to guide students in their analysis of EU policy-making.
