Britain's candidates are campaigning from Cornwall in southwestern England to the far northern reaches of Scotland in search of votes with the general election just two days away.

Polls suggest the race is extremely close and no clear trend has emerged. Many believe no party will win a majority, leading to a hung Parliament and a period of negotiations before a new government emerges.

Prime Minister David Cameron from the Conservatives and Labour Party leader Ed Miliband are virtually even in last-minute surveys despite weeks of intense campaigning.

Liberal Democrat leader Nick Clegg, who hopes to play kingmaker, plans a 1000-mile bus tour in the campaign's final days.

He said Tuesday there is no way Cameron or Miliband will gain a majority, leaving his party to provide stability.
