The 1931 United Kingdom general election was held on Tuesday, 27 October 1931. It saw a landslide election victory for the National Government, a three-party coalition which had been formed two months previously after the collapse of the second Labour government. Journalist Ivor Bulmer-Thomas described the result as "the most astonishing in the history of the British party system".
Unable to secure support from his cabinet for his preferred policy responses to the economic and social crises brought about by the Great Depression, Prime Minister Ramsay MacDonald split from the Labour Party and formed a new national government in coalition with the Conservative Party and a number of Liberals. MacDonald subsequently campaigned for a "Doctor's Mandate" to do whatever was necessary to fix the economy, running as the leader of a new party called National Labour within the coalition. Disagreement over whether to join the new government also resulted in the Liberal Party splitting into three separate factions, including one led by former Prime Minister David Lloyd George.
