Directorate-General
Within the European Union, Directorates-General are departments with specific zones of responsibility. Within the European Commission specifically, Directorates-General are the equivalent of national-level ministries. Most are headed by a European commissioner, responsible for the general direction of the Directorate-General, and in charge of the corresponding policy area; and a director-general, responsible for the management of day-to-day affairs, who reports to the European Commissioner.
Nearly all of the top-level organisational divisions of the Secretariat of the European Parliament and the General Secretariat of the Council of the European Union are also termed Directorates-General.
The European Patent Office also has Directorates-General, which are administrative groupings of departments.
