Reform Act

In the United Kingdom, Reform Act is legislation concerning electoral matters. It is most commonly used for laws passed in the 19th century and early 20th century to enfranchise new groups of voters and to redistribute seats in the House of Commons of the Parliament of the United Kingdom.
Reform Acts.
The parliamentary franchise in the United Kingdom was expanded and made more uniform through a series of Reform Acts beginning with the Great Reform Act in 1832. Sources refer to up to six "Reform Acts", although the earlier three in 1832, 1867/8 and 1884 are better known by this name. Some other acts related to electoral matters also became known as Reform Acts. There are many other electoral reform acts in the United Kingdom that are not known by the name "Reform Act". Such legislation typically used the short title of Representation of the People Act, by which name the 1918, 1928 and other acts in the 20th century are better known.
Modern usage.
The periodic redrawing of constituency boundaries is now dealt with by a permanent Boundary Commission in each part of the United Kingdom, rather than by a Reform Act.
Some people in Britain, mostly associated with the Liberal Democrat political party, have called for a new "Great Reform Act" to introduce electoral changes they favour. These would include lowering the minimum voting age to 16 and introducing proportional representation.
