The 1935 general election resulted in victory for the National Government (consisting principally of the Conservative Party, along with the Liberal National Party and the National Labour Organisation) by a substantial majority. Stanley Baldwin became Prime Minister. In May 1937, Baldwin retired and was succeeded by Neville Chamberlain who continued Baldwin's foreign policy of appeasement in the face of German, Italian and Japanese aggression. Having signed the Munich Agreement with Hitler in 1938, Chamberlain became alarmed by the dictator's continuing aggression and, in August 1939, signed the Anglo-Polish military alliance which guaranteed British support for Poland if attacked by Germany. Chamberlain issued the declaration of war against Germany on 3 September 1939 and formed a war cabinet which included Winston Churchill (who had been out of office since June 1929) as First Lord of the Admiralty and Viscount Halifax as Foreign Secretary.
