The United Kingdom general election of 2010 was held on Thursday 6 May 2010 to elect members to the House of Commons. The election took place in 650 constituencies across the United Kingdom under the first-past-the-post system. None of the parties achieved the 326 seats needed for an overall majority. The Conservative Party, led by David Cameron, won the largest number of votes and seats but still fell twenty seats short. This resulted in a hung parliament where no party was able to command a majority in the House of Commons. This was only the second general election since World War II to return a hung parliament, the first being the February 1974 election.
