David Cameron is expected to acknowledge a failure to properly explain the reasons behind the Coalition's tough economic measures, in a speech later.
The Prime Minister will say: "Too often we've given the impression that we're just about fixing problems rather than changing things for a purpose.
"But that completely misunderstands what we're trying to do."
Mr Cameron will stress that Government cuts are based on "values", specifically getting to grips with the deficit and giving people "a sense of economic security".
The Government's spending cuts are not being made for their own sake but are instead based on "values", David Cameron is expected to say.
In speech later, the Prime Minister will say the Coalition's austerity programme is designed to "give people a sense of economic security and peace of mind".
He said that security came from "having more money in our pockets", saying "every efficiency" found could help provide "a bit of extra cash" for hard-pressed families.
