The European Council (French: Conseil européen), charged with defining the EU's overall political direction and priorities, is the institution of the European Union (EU) that comprises the heads of state or government of the member states, along with the President of the European Council and the President of the European Commission. The High Representative of the Union for Foreign Affairs and Security Policy also takes part in its meetings. Established as an informal summit in 1975, the European Council was formalised as an institution in 2009 upon the entry into force of the Treaty of Lisbon. Its current President is Donald Tusk.
