The JIC members discussed a vast range of international and domestic issues in their meetings. In this file, subjects documented include the security of foreign embassies; encryption and the potential interception of communications; Anglo-French military and intelligence cooperation, including plans for the defence of the Mediterranean and East Africa against Italian invasion; appreciations of the Soviet Union's military forces and the state of the armaments and supply situation of Poland; the organisation of military missions to Eastern Europe; and the organisation of British intelligence services, including the creation of a new Middle East Intelligence Centre.
