With just a few days to go before Britain's general election, the leaders of the three main parties spent Friday campaigning around England.

Conservative leader David Cameron got an apparent boost after polls put him on top in Thursday night's final televised leaders' debate.

The strong showing raises Conservatives' hopes of victory on May 6th election after 13 years as opposition to Labour governments.

David Cameron, leader of Conservative Party, said, "This election is far from over, we are now entering the most energetic and the most important stage of this campaign."

Brown was the favorite heading into Thursday night, but his delivery was flat.

He also looked tired after a day-long political maelstrom caused by the broadcast of his private comments describing a woman as a "bigot".

But he vowed to keep fighting.

Gordon Brown, leader of Labour Party, said, "The time for debates has finished, and the time for decision has begun."

Former Prime Minister Tony Blair, who brought Labour to power some 12 years ago, joined the campaign trail on Friday, stumping for Brown.

He appealed to voters to judge his successor on policy, not personality.

Former Prime Minister Tony Blair said, "I think if people actually look and listen to the substance, they'll see somebody who is completely on top of his facts, knows exactly the policies that he believes the country should follow."

Liberal Democrats leader Nick Clegg has now emerged as a credible contender.

Support for the Liberal Democrats is up dramatically to about 30 percent in opinion polls, a major jump from 18 percent.

This is the closest British election campaign in nearly 20 years and appears headed for an inconclusive result. Opinion polls suggesting the main opposition Conservatives are in the lead, but are not in a position to secure a majority in parliament.
