The prime minister launched the Conservative campaign in the May 2 local elections with a speech at a sports club in Nuneaton, The Daily Telegraph reported.
He reminded party activists of the Conservative role in freezing local council taxes and said low taxes are a "moral imperative."
"We're fighting for the pound in your pocket in fact -- we're fighting to keep it there," Cameron said. "Because Conservatives get something. It's your money. Every single pound has been hard-earned -- early mornings, late nights, long commutes, time away from the children, hours put in on the factory floor, the shop floor, the hospital ward."
Labor Party leaders have accused the Conservative-Liberal Democrat coalition government of making cuts in government services that foster "the break-up of civil society." Cameron accused some Labor-dominated councils of spending money on high salaries and perks.
