Representation of the People Acts, (1918, 1928) parliamentary acts that expanded suffrage in Britain. The act of 1918 gave the vote to all men over age 21 and all women over age 30, which tripled the electorate. The act of 1928 extended the franchise to women aged 21–30. The acts continued the voting reforms begun by the Reform Bills of 1832, 1867, and 1884–85.
