Areas so far protected from austerity to be targeted after 2015George Osborne will pledge to introduce even deeper spending cuts after the next general election by imposing a new cap on parts of the welfare budget and other areas which have so far been immune from the coalition's austerity plans.As the chancellor served notice that Britain faces a longer-than-expected recovery, after the Office for Budget Responsibility halved its growth forecast for this year, a senior Treasury source said Osborne would promise to target so called "annually managed expenditure" (AME) in the next parliament.This accounts for about 50% of government spending – covering many areas of welfare, debt interest and EU contributions – and has largely not been targeted during the current round of spending cuts.
