"The United Kingdom general election of 2010 will be held on 6 May[note 1] to elect one MP in each of the 650 constituencies to the House of Commons, the lower house of the Parliament of the United Kingdom. The election was called on 6 April, and Parliament was dissolved on 12 April for the ensuing campaign. Voting will take place between 7.00 am and 10.00 pm. Local elections will also be held in some areas on that day.
The governing Labour Party will be looking to secure a fourth consecutive term in office and to restore support lost since 1997. The Conservative Party will seek to gain a dominant position in UK politics after losses in the 1990s, and to replace Labour as the governing party. The Liberal Democrats hope to make gains from both sides; their most realistic ambition, as the campaign began, was to hold the balance of power in a hung parliament. Since the televised debates between the three leaders, their poll ratings have risen to the point where many are considering the possibility of a Liberal Democrat role in Government.
