Budget 2013: Osborne to unveil extra £2.5bn in cuts
The government is to announce further spending cuts in Wednesday's Budget, with the savings going to large-scale infrastructure projects designed to boost economic growth.
Most Whitehall departments will have to cut 2% of their spending over the next two years, amounting to about £2.5bn.
But health, schools and HM Revenue & Customs budgets will be unaffected.
