Churchill's 'Iron Curtain' speech

Churchill had lost power following a crushing election defeat in Britain in 1945. Encouraged by the US President Harry Truman, Churchill agreed to give a speech on world affairs at Westminster College in Fulton, Missouri. But why did the speech have such an impact. Alex Last hears from the historian Prof David Reynolds of Cambridge University, author of The Kremlin Letters: Stalin's wartime correspondence with Churchill and Roosevelt.
