Shadow chancellor George Osborne has promised to publish detailed departmental spending cuts by the autumn if the Tories win the forthcoming general election.
A Tory administration would work "flat out" over the summer identifying the "difficult decisions" necessary to bring down the country's massive deficit, he said.
Those measures would be based on the findings of an independent audit of the public finances, and forecasts for growth, that would be carried out soon after polling day.
Mr Osborne set out the timetable as he delivered the annual Mais Lecture in the City of London.
He will now take his message on the economy to the West Midlands where he will meet members of the region's business community.
An emergency budget would then be held within 50 days of the election, setting out the "overall fiscal path and spending totals" for the years ahead, he said.
That would include measures to reduce the public sector pensions bill and the cost of Whitehall bureaucracy, as well as increasing the pension age.
But it would also feature support for enterprise to "encourage new jobs and show that Britain is open for business", Mr Osborne said.
The Tories would then set to work on the departmental spending review that Mr Osborne accused the Government of shying away from.
Labour criticised Mr Osborne for failing to offer "any plan" for dealing with the deficit.
