The United Kingdom general election of 2010 resulted in a hung parliament and a coalition government of Conservatives and the Liberal Democrats. Thus the Conservative Party came into power after 13 years in Opposition，while the Liberal Democrats became a party of government for the first time in its history. British politics entered a new era. The coalition government has generally run smoothly in the first two-and-a-half years；however，the differences in ideology and party interests between the two parties have also emerged. The Labour Party elected Ed Miliband as new leader，who proposed“One Nation Labour”as a new ideology，and has been preparing for the next general election. Moreover，the influence of the UKIP has been increasing，and it has shown the potential to displace the Liberal Democrats as the third force in British Politics.
