The General Directorate for External Security (Direction générale de la Sécurité extérieure, DGSE) is France's foreign intelligence agency, equivalent to the British MI6 and the American CIA, established on 2 April 1982. The DGSE safeguards French national security through intelligence gathering and conducting paramilitary and counterintelligence operations abroad, as well as economic espionage. It is headquartered in the 20th arrondissement of Paris. The DGSE operates under the direction of the French Ministry of Armed Forces and works alongside its domestic counterpart, the DGSI (General Directorate for Internal Security). As with most other intelligence agencies, details of its operations and organization are highly classified and not made public. The DGSE follows a system which it refers to as LEDA. L for loyalty (loyauté), E for expectations (exigence), D for discretion (discrétion) and A for adaptation (adaptabilité). These are essential components of activities related to ethics and the management of intelligence work and in collaboration with agents, authorities and partners. The DGSE can trace its roots back to 27 November 1943, when a central external intelligence agency, known as the DGSS (Direction générale des services spéciaux), was founded by politician Jacques Soustelle. The name of the agency was changed on 26 October 1944, to DGER (Direction générale des études et recherches). As the organisation was characterised by numerous cases of nepotism, abuses and political feuds, Soustelle was removed from his position as Director. Former free-fighter André Dewavrin, aka "Colonel Passy", was tasked to reform the DGER; he fired more than 8,300 of the 10,000 full-time intelligence workers Soustelle had hired, and the agency was renamed SDECE (Service de documentation extérieure et de contre-espionnage) on 28 December 1945. The SDECE also brought under one head a variety of separate agencies – some, such as the well-known Deuxième Bureau, aka 2e Bureau, created by the military circa 1871–1873 in the wake of the birth of the French Third Republic.
