They can announce cuts, they can announce increases, they can set the whole thing to music and do a karaoke
David Cameron
David Cameron has said ministers are trying to "cover up the truth about Labour's cuts".
The Conservative leader, speaking at a press conference on Monday, also slammed Gordon Brown, saying there is a "thread of dishonesty" running through his premiership.
His comments came after business secretary Lord Mandelson indicated there would be no spending review before the next general election.
Cameron said the move was part of a "pattern of deception" seen in recent rows over the funding of public services.
The prime minister has repeatedly attacked the Tories for planning "10 per cent cuts" in key departments.
But the Conservative leader said Labour would also have to cut spending levels.
"Cancelling the spending review is nothing to do with economic uncertainty and everything to do with political manoeuvring," he said.
"It is a blatant attempt to cover up the truth about Labour's cuts."
"We shouldn't be surprised," he added. "I believe there is a thread of dishonesty running through this premiership.
"From cancelling the election and then saying it had nothing to do with the opinion polls, to his claim that abolishing the 10p income tax [rate] would have nothing to do in terms of hitting the poor.
"We've had his insistence that Alistair Darling is his first choice as chancellor, and now this frankly pattern of deception about public spending."
While attacking Labour's honesty, Cameron refused to directly brand the prime minister a liar.
"I don't care what the government does any more," he said.
"They can announce cuts, they can announce increases, they can set the whole thing to music and do a karaoke.
"I've completely lost faith, and I think most of the country has lost faith, in anything this government says."
