Speaking at a Labour campaign dinner in Putney, south-west London on 11 June, Blears said Conservative leader David Cameron was not a "convinced localist" who was trying to win power in order to devolve it.
"No, he's engaged in an enormous con trick," she said. "His enthusiasm for localism, for the third sector, for volunteering must be seen in the context of his political philosophy, which is right-wing conservatism.
"A smaller state. Reduced public expenditure. Tax cuts for the rich. And real cash cuts to local government, the NHS, the police, schools and the transport system. And the role of voluntary activity in this situation is not as a partner to a progressive central government, but a safety net for the most vulnerable."
Blears said philanthropy and voluntarism should be encouraged, but that it should never be viewed as a way of getting public services "on the cheap".
