The Reform Act 1832, formally the Representation of the People Act 1832, reformed the electoral system in England and Wales and expanded the franchise. It was brought forward by the Whig government of Prime Minister Charles Grey, 2nd Earl Grey, and is also known as the Great Reform Act or First Reform Act.
The Reform Act 1832 received royal assent on the 7th of June 1832. King William IV had earlier agreed to create enough new Whig peers to force the bill through the House of Lords if that proved necessary.
The Reform Act 1832 formally excluded women from voting by defining a voter as a male person. Before 1832 there had been occasional, rare instances of women voting under earlier property-based rules.
The Reform Act 1832 abolished 143 borough seats in England, removing all representation from 56 boroughs and one seat each from 30 more. In their place, it created 130 new seats across England and Wales, including new county divisions and representation for large towns.
Public anger followed the House of Lords' rejection of the bill in October 1831, when it failed by 41 votes. Riots broke out in Derby, Nottingham, and Bristol, where a mob controlled the city for three days and destroyed the Bishop of Bristol's palace.
The Reform Act 1832 was repealed by the Representation of the People Act 1948, effective from the 30th of July 1948. The UK electoral system is now defined principally by the Representation of the People Act 1983 and the Electoral Administration Act 2006.
