The 1929 United Kingdom general election was held on Thursday 30 May 1929, and resulted in a hung parliament. It was the second of four general elections under the secret ballot and the first of three under universal suffrage in which a party lost the popular vote (i.e. gained fewer popular votes than another party) but gained a plurality of seats—the others of the four being 1874, 1951 and February 1974. In 1929 that party was Ramsay MacDonald's Labour Party, which won the most seats in the House of Commons for the first time, but failed to get an overall majority. The Liberal Party led by David Lloyd George regained some of the ground it had lost in the 1924 election, and held the balance of power.
The election was often referred to as the "Flapper Election", because it was the first election in which women aged 21–29 were allowed to vote, under the provisions of the Representation of the People Act 1928. (Women over 30 had been able to vote since the 1918 election.)
The election was fought against a background of rising unemployment, with the memory of the 1926 general strike still fresh in voters' minds. By 1929, the Cabinet was being described by many as "old and exhausted".
The Liberals campaigned on a comprehensive programme of public works under the title "We Can Conquer Unemployment". The incumbent Conservatives campaigned on the theme of "Safety First", with Labour campaigning on the theme of "Labour & the Nation".
