The European Union (EU) has several key institutions that help it function effectively. The European Commission proposes new laws and ensures that EU policies are implemented. The European Parliament represents the citizens of the EU and works with the Commission to pass legislation. Another important institution is the European Council, which consists of the heads of state or government of EU countries. It sets the overall direction and priorities of the EU. Lastly, the Court of Justice of the European Union ensures that EU law is interpreted and applied consistently across all member states.
