The 1831 United Kingdom general election saw a landslide win by supporters of electoral reform, which was the major election issue. As a result, it was the last unreformed election, as the following Parliament ensured the passage of the Reform Act 1832. Polling was held from 28 April to 1 June 1831. The Whigs won a majority of 136 over the Tories, which was as near to a landslide as the unreformed electoral system could deliver. As the Government obtained a dissolution of Parliament once the new electoral system had been enacted, the resulting Parliament was a short one and there was another election the following year. The election was the first since 1715 to see a victory by a party previously in minority.
