London: Britain's Conservative Party of Prime Minister David Cameron is headed for a simple majority, having already secured 300 of the total 650 seats in the House of Commons, a media report said on Friday.

Ed Miliband's Labour Party has secured 220 seats, the Scottish National Party (SNP) 56, and the Democratic Unionist Party and the Liberal Democrats (Lib Dems) are tied at eight, BBC reported.

BBC is projecting 329 seats for the Conservatives. The magic figure for simple majority in the house is 326.

Labour Party has been all but wiped out by the SNP in Scotland and is failing to make enough gains in England and Wales.

The Lib Dems are heading for as few as eight MPs, with Vince Cable, Ed Davey and Danny Alexander losing their seats.

Cameron said it was "too early to say" the final result but he hoped to form a government.

"My aim remains simple - to govern on the basis of governing for everyone in our United Kingdom," Cameron said during his victory speech after being returned as MP for Witney county constituency in Oxfordshire.

"I want to bring our country together, our United Kingdom together, not least by implementing as fast as we can the devolution that we rightly promised and came together with other parties to agree both for Wales and for Scotland."

"In short, I want my party, and I hope a government I would like to lead, to reclaim a mantle that we should never have lost - the mantle of One Nation, One United Kingdom," the prime minister added.
