European Council

The European Council (referred to as a European Summit) is the highest political body of the European Union. It is made of all the heads of state or government of the Union's member states and with the President of the European Commission. The country which holds the Presidency of the Council of the European Union also leads its assemblies.
The Council has no formal executive or legislative powers. It is an institution that deals with very important issues and any decisions made are "a major impetus in defining the general political guidelines of the European Union". The Council meets at least twice a year; usually in the Justus Lipsius building, the quarters of the Council of the European Union (Consilium) of Brussels.
