The 1929 United Kingdom general election was held on Thursday, 30 May 1929, with Parliament dissolved on 10 May. It resulted in a hung parliament: despite receiving fewer votes than the Conservative Party, led by Prime Minister Stanley Baldwin, Ramsay MacDonald's Labour Party won the most seats in the House of Commons, with the Liberal Party, led again by former Prime Minister David Lloyd George, regaining some of the ground lost in 1924 and holding the balance of power.
The election was often referred to as the "Flapper Election", because it was the first in which women aged 21–29 had the right to vote (owing to the Representation of the People Act 1928). Women over 30, with some property qualifications, had been able to vote since the 1918 general election, but the 1929 vote was the first general election with universal suffrage for adults over 21, which was then the age of majority.
