The results also showed that among the decided seats, the Labor Party won 244, with 51 for the Liberal Democratic Party and 27 for the others.

"What is clear from these results is that the country, our country, wants change," Cameron said Friday after he was announced as the winner in Witney, west of England.

The 2010 election is highly unusual in British politics. It has largely been a three-horse campaign, and all elections since just after the First World War have been two-horse races, and it looks like producing an election rarity, a hung parliament.

That has not happened since February 1974, when a minority Labour government took control and then declared another election just eight months later in a bid for a stronger mandate.
