Le Cercle is a foreign policy think-tank specialising in international security. Set up after World War II, the group has members from twenty-five countries and meets at least bi-annually, in Washington, D.C., United States.
Le Cercle has operated in anonymity since its creation, with only a handful of articles having been written about it. The Cercle was mentioned in the early 1980s by Der Spiegel in Germany as a result of the controversy surrounding Franz Josef Strauß, one of the regular attendants of the Cercle. In the late 1990s, the Cercle received some attention after a scandal had broken out involving Jonathan Aitken, at the time chairman of Le Cercle. Members that were contacted by newspapers refused to answer any questions.
