The Foreign Office and Foreign Policy, 1919-1926 tells of the administrative changes of the post-war period and of the senior permanent officials, their personalities and cast of mind, who advised the foreign secretary and carried out his policies. The book goes beyond existing accounts of changes taking place after the Great War, and provides examples of the FO machine in action as seen from King Charles Street, and the uneasy relationship between 10 Downing Street and the Foreign Office.
