The National Government of August–October 1931, also known as the First National Government, was the first of a series of national governments formed during the Great Depression in the United Kingdom. It was formed by Ramsay MacDonald as Prime Minister of the United Kingdom following the collapse of the previous minority government, led by the Labour Party, known as the Second MacDonald ministry.
As a National Government, it was dominated by members of the Conservative Party, and also included a few from Liberals and National Labour, as well as individuals who belonged to no political party. The breakaway Liberal Nationals supported the National Government after their formation in September 1931 but none received posts in the new administration. Subsequently, two Liberal ministers, Alec Glassey and John Pybus, defected to the Liberal Nationals. It did not contain members of the Labour Party as MacDonald had been expelled from it. The Labour Party led the opposition.
