David Cameron Wins UK Parliamentary Elections

David Cameron has won an unexpected majority in the UK's parliamentary elections, overturning poll predictions and sweeping the Conservatives to power, as three of his election rivals quit following their disastrous turnout at the polls.

The Conservative Party managed to secure 326 seats after 643 constituencies were counted, to the Labour party's 230 seats, and eight for the Liberal Democrat party.

"This is clearly a very strong night for the Conservative Party," Cameron said.

Striking a conciliatory tone with his rivals, he promised to govern as the party of "one nation, one United Kingdom," after the election was brought to a much-quicker-than-expected conclusion.

"We can make Britain a place where a good life is in reach for everyone," he said.

Cameron, who will be the first Conservative prime minister to win a second term since Margaret Thatcher, also vowed to counter the rise of Scottish nationalism with more powers for Scotland and Wales.

Polls ahead of Election Day had shown Conservatives locked in a tight race with the opposition Labour Party, raising the possibility of days or weeks of negotiations to form a government.
