The Conservative Party plans to use the wisdom of crowds to unpick Alistair Darling's Budget tomorrow.
"We are going to crowd source the Budget," Conservative leader David Cameron said.
"We know the form by now with Labour's Budgets. There is a whole load of giveaways up front while all the nasty stuff is stashed away in the small print," he said.
The Conservatives plan to publish the Budget page-by-page on its website "so that everyone can have a dig around" to see what the fine print hides.
"We want people to log on, have a look, pick out the misleading bits and help us hold Labour to account," he said.
Cameron was speaking in the wake of Labour's suspension of three former cabinet ministers for allegedly soliciting money for influencing ministerial decisions.
