The Representation of the People (Equal Franchise) Act 1928 was an Act of the Parliament of the United Kingdom. This act expanded on the Representation of the People Act 1918 which had given some women the vote in Parliamentary elections for the first time after World War I. The 1928 Act widened suffrage by giving women electoral equality with men. It gave the vote to all women over 21 years old, regardless of property ownership. Prior to this act only women over 30 who met minimum property qualifications could vote. Similar provision was made for the Parliament of Northern Ireland by the Representation of the People Act (Northern Ireland) 1928 (18 & 19 Geo V, Ch 24 (NI)).
This statute is sometimes known informally as the Fifth Reform Act or the Equal Suffrage Act.
The bill became law on 2 July 1928, having been introduced in March. The leader of the National Union of Women's Suffrage Societies who had campaigned for the vote, Millicent Fawcett, was still alive and attended the parliament session to see the vote take place. She wrote in her diary the same night "It is almost exactly 61 years ago since I heard John Stuart Mill introduce his suffrage amendment to the Reform Bill on 20 May 1867. So I have had extraordinary good luck in having seen the struggle from the beginning."
