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.
At some point in the 1950s, Le Cercle was established by former French prime minister Antoine Pinay and French intelligence agent Jean Violet under the name Cercle Pinay.
Le 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.
