It consists of the Heads of State or Government of the Member States, together with its President and the President of the Commission. The High Representative of the Union for Foreign Affairs and Security Policy takes part in its work. The European Council defines the general political direction and priorities of the European Union. It does not exercise legislative functions. The European Council meets twice every six months, convened by its President. When the situation so requires, the President will convene a special meeting. The President's term of office is two and a half years, renewable once. The European Council usually meets in Brussels.
It is the EU’s principal decision-taking body. It shares with the European Parliament the responsibility for passing EU laws. The Council of the EU consists of ministers from the national governments of all the EU countries. Meetings are attended by whichever ministers are responsible for the items to be discussed. Every six months, a different member state assumes the so-called Presidency of the EU, meaning that it chairs these meetings and sets the overall political agenda. The rotating presidency does not apply to the Foreign Affairs Council, which is chaired by the EU's High Representative for Foreign Affairs and Security Policy.
It is the EU’s executive body and represents the interests of the EU as a whole. It drafts proposals for new European laws, which it presents to the European Parliament and the Council. It puts into practice the EU's common policies and manages the EU's funds and programmes. The Commission also plays its role as "guardian of the treaties" making sure that everyone abides by the EU treaties and laws. It can act against rule-breakers, taking them to the European Court of Justice if necessary.
The Commission consists of 27 Commissioners — one from each EU country. The president of the Commission is chosen by the 27 EU governments and endorsed by the European Parliament. The other commissioners are nominated by their national governments in consultation with the incoming president, and must be approved by the European Parliament. They do not represent the governments of their home countries. Instead, each of them has responsibility for a particular EU policy area. They are all appointed for a period of five years.
