In 2010, the Conservative Party were the largest party with 306 seats. But, they were short of a majority so formed a coalition with the Liberal Democrats.
The 2010 election followed the 2008 financial crisis which took place when Gordon Brown was prime minister, and gave the Conservatives a means to attack his policies and time as leader.
Brown was unpopular for not calling a general election when he took over as prime minister from Tony Blair in 2007.
Voters did not clearly favour the Conservatives over Labour, with polls suggesting 29% of voters felt that the Conservatives would be best for managing the economy compared to 26% for Labour.
Television debates were held with the three main party leaders David Cameron, Gordon Brown and Nick Clegg.
Nick Clegg performed particularly well and saw an increase in the opinion polls after the first debate, whilst Gordon Brown was seen to have performed worse.
The Conservatives targeted marginal seats and market-tested their policies with voters, whilst Labour had a weak campaign.
Gordon Brown was heard calling a voter a ‘bigoted woman’ who had asked him about immigration.
The main parties all focused on policies to reduce the budget deficit and making savings.
The Conservatives stated the need for immediate cuts, whilst Labour and the Liberal Democrats wanted more gradual public spending cuts.
The Conservatives targeted Labour’s economic policy in government, which they said included overspending and failing to regulate the banking system. This was a successful approach and a view shared by voters.
Conservatives, David Cameron, 306 seats won. Liberal Democrats, Nick Clegg, 57 seats won. Labour, Gordon Brown, 258 seats won.
Age has become a more important factor in determining UK voting behaviour.
In 2010 there was a large difference among older voters, with 44% of voters aged over 65 supporting the Conservatives compared to 31% of voters supporting Labour.
In 2010 class played less of a role with the Conservatives winning the most middle-class support, at 39%, and Labour narrowly winning the most support of the unskilled working class.
The Conservatives won more support from the skilled working class, despite this group mainly supporting Labour in previous elections.
In 2010 higher percentages of both men and women supported the Conservative party than any other party.
In 2010 Labour and the Conservatives received similar levels of support across men and women.
This suggests that gender has had less of an impact on voting behaviour in more recent years
