After the TV debate, Liberal Democrats have surged in the polls but are predicted to win even fewer seats than at the 2005 election.

According to Sky News, Cameron said the projected result is still enough for his party to take power. "Exit poll is decisive rejection of labor and we can govern with this result," a spokesman for the party said.

Labor's Deputy leader Harriet Harman said "it is very much too early to say" the outcome of the vote.

In the event of a hung parliament, Prime Minister Gordon Brown, also leader of Labor Party, is entitled to remain prime minister to see if he can command the confidence of the House of Commons.

The findings were announced as voting closed at 10 p.m. local time (2100 GMT). Exit poll result was formed by the responses of about 17,000 voters across 130 polling stations. Counting was to continue through the night, and the winner would not be officially confirmed at least until Friday morning.

This exit poll was an accurate prediction of the eventual result at the last general election in 2005, but this election is the most difficult to predict in decades.

To form a majority government one party needs to win 326 seats in parliament out of a total of 650. Each seat contains a member of parliament elected by individual geographic constituencies under the first-past-the-post system which rewards the winner, but gives nothing to the losers in the constituency races.

The poll showed that Britain is heading for a hung parliament although the Conservatives are ahead during the three-horse race.
