Britain's opposition Conservative party leader David Cameron on Tuesday launched the general election manifesto ahead of the May 6 elections, inviting voters to join them in government.

The 130-page document highlighted a series of policies which the Tories say will enable people to take greater control of their own lives.

Cameron formally unveiled his plans entitled Invitation to Join the Government of Britain at Battersea Power Station in south London. The Conservative party pledges to help people to sack members of parliament, give people power to veto high council tax increase and to elect police commissioners.

Cameron said "Parents, charities, businesses, neighborhoods, every citizen, the entire nation" - everyone can join him and take control. "The alternative to big government is not no government, it's good government."

He said the Conservatives could make things better without spending more money and will help the poorest, protect the National Health Service, help people find work and support families.

Moving on to political reform, Cameron said "the best apology we can give to the British people for the expenses scandal is to hand power back to them."

He wants a Tory government to cut the cost of politics - freezing ministers' pay and the cutting the numbers of parliamentary members.

In his foreword to the manifesto, Cameron said the problems facing Britain can only be resolved if Britain "pulls together."

"Real change comes not from government alone. Real change comes when the people are inspired and mobilized, when millions of us are fired up to play a part in the nation's future," he said.

Britain's ruling Labor Party launched its election manifesto on Monday, pledging not to raise income tax and more public service reform as it bids for a fourth term in office.

This week is manifesto week in the British general election campaign. On Wednesday it is the turn of the Liberal Democrats.
