President of the European Council the member state holding the semiannually rotating Presidency of the Council of the European Union at any given time. However, since the 2007 Treaty of Lisbon, article 15 of Treaty on European Union states that the European Council appoints a full-time president for a two-and-a-half-year term, with the possibility of renewal once. Appointments, as well as the removal of incumbents, require a double majority support in the European Council. On 19 November 2009, the European Council agreed that its first president under the Lisbon Treaty would be Herman Van Rompuy (European People's Party, Belgium). Van Rompuy took office when the
President of the European Council Lisbon Treaty came into force on 1 December 2009 with a term stretching until 31 May 2012. His term was later extended with a second period ending on 30 November 2014. The current president, for the term 1 June 2017 until 30 November 2019, is the former Polish Prime Minister Donald Tusk. He was reelected on 9 March 2017. The first meeting of all EU (then EC) heads of state or government was held in 1961 as an informal summit, but only became formalised in 1974, when it was baptised "European Council" by the then French president Valéry Giscard d'Estaing.
