In the United Kingdom under the premiership of William Gladstone, the Representation of the People Act 1884, also known informally as the Third Reform Act, and the Redistribution Act of the following year were laws which further extended the suffrage in the UK after the Derby government's Reform Act 1867. Taken together, these measures extended the same voting qualifications as existed in the towns to the countryside, more than doubling the electorate in the counties, and essentially established the modern one member constituency as the normal pattern for parliamentary representation.

William Ewart Gladstone was a British statesman and Liberal politician. In a career lasting over 60 years, he served for 12 years as Prime Minister of the United Kingdom, spread over four non-consecutive terms beginning in 1868 and ending in 1894. He also served as Chancellor of the Exchequer four times, for over 12 years.
