The main institutions are:
The aim of the EU is to benefit its members through enabling free movement of people, goods, services, and capital, applying common standards of justice, and maintaining common policies on trade, agriculture, fisheries, and regional development. Examples of EU policies and institutions which aim to bring these benefits include the abolition of passport controls within the Schengen Area, the introduction of the monetary union (the euro), and the European Court of Human Rights.
The EU is founded on the principle of ‘conferral of competences’:
The EU needs to balance both the rights and needs of the Union as a whole, and of the individual member states. The unique institutional set-up is intended to achieve this:
This is a difficult balance to achieve, and not everyone agrees that the EU achieves the right balance of power between individual member states, and between members states and the Union as a whole.
The European Parliament
The European Parliament, together with the Council of the EU, makes up the legislative arm of the EU. It consists of 751 Members of the European Parliament who are directly elected every five years (in the UK, MEP elections often coincide with local council elections). The number of MEPs representing each member state is roughly proportional to its population. One MEP is elected President, and they represent the Parliament to other EU institutions and internationally.
The European Parliament has similar functions to the UK Parliament: it passes EU laws, together with the Council of the EU, it sets the EU budget, and it retains democratic scrutiny of all EU institutions.
The European Council
The European Council consists of the heads of all member states, the European Commission President, and the High Representative for Foreign Affairs & Security Policy. The Council is convened and chaired by its President, who is elected by the European Council itself for a once-renewable two-and-a-half-year term. The President represents the EU to the outside world.
The Council decides on the EU's overall direction and political priorities – but does not pass laws. It sets the EU’s common foreign and security policy, and deals with sensitive or complex issues that cannot be resolved at a lower level. It represents the highest level of political cooperation between EU countries.
The European Commission
The European Commission is the EU's politically independent executive arm. It consists of team of Commissioners, one from each member state, led by the President. The presidential candidate is put forward by national leaders in the European Council, taking account of the results of the European Parliament elections. He or she needs the support of a majority of members of the European Parliament in order to be elected.
The Commission is alone responsible for drawing up proposals for new European legislation, and it implements the legislative decisions of the European Parliament and the Council of the EU. It also sets EU spending and policy priorities, and represents the EU internationally.
Together with the Court of Justice, it ensures that EU law is properly applied in all member states.
The day-to-day running of Commission business is performed by its staff (lawyers, economists, etc.), organised into departments known as Directorates-General, each responsible for a specific policy area. These are analogous to UK government departments.
The Council of the European Union
The Council of EU is the voice of EU member governments, and is where government ministers from each member state meet to discuss, amend and adopt laws, and coordinate policies. Its makeup is not fixed, but changes according to the policy issues under consideration. Together with the European Parliament, the Council is the main legislative body of the EU. The Council’s role is to:
Each EU country holds the Council Presidency on a six-month rotating basis.
