The secretary-general of the Council of the European Union heads the General Secretariat of the Council of the European Union. In October 2022, the Council appointed Thérèse Blanchet as the Secretary-General of the Council for a five-year term, from 1 November 2022 to 31 October 2027.
Previously, the post holder was also the High Representative for the Common Foreign and Security Policy, President of the European Defence Agency and the Western European Union. The Treaty of Amsterdam, which entered into force in 1999, created the office of the High Representative for the Common Foreign and Security Policy and specified that the Secretary-General would occupy that position simultaneously. Javier Solana exercised both functions from 1999 until 2009. The Lisbon Treaty, which took effect on 1 December 2009, redefined the post of High Representative and again separated it from the office of Secretary-General of the Council.
