Chancellor George Osborne has revealed which Government departments will bear the brunt of his CSR spending cuts.
He unveiled wide-ranging proposals to cut the UK's record budget deficit while protecting the economy. There will be overall savings in funding to local councils of 7.1%, but ring-fencing of all local government revenue grants will end from April next year, except for simplified schools grants and a public health grant.
The Government will deliver £6 billion of Whitehall savings - double the £3 billion promised earlier - and the core Cabinet Office budget will be reduced by £55 million by 2014/15.
The Foreign Office budget will see savings of 24% through a sharp reduction in the number of Whitehall-based diplomats and back office functions, but the Department for International Development's budget will rise to £11.5 billion over the next four years, reaching 0.7% of national income in 2013.
Other losers will be Home Office and the Ministry of Justice, which face annual budget cuts of 6% - with policing down 4%.
The state pension age for men and women will reach 66 by the year 2020, saving over £5 billion a year by the end of the next Parliament. The Ministry of Defence budget will reach £33.5 billion in 2014/15, a saving of 8%, the Chancellor confirmed.
Mr Osborne said total public expenditure will g£702 billion next year, then £713 billion the year after that, £724 billion then next year and £740 billion by 2014/15. He said debt interest payments will be lower by £1 billion in 2012, £1.8 billion in 2013 and £3 billion in 2014 - a total of £5 billion over the course of the spending review.
The average saving in departmental budgets will be lower than the Labour government implied, the Chancellor said, with cuts of 19% over four years instead of 20%.
The Ministry of Defence budget will reach £33.5 billion in 2014/15, a saving of 8%, the Chancellor confirmed.
The Treasury itself will see its overall budget reduced by 33% and the department's building will be shared with part of the Cabinet Office. Meanwhile, HM Revenue and Customs's budget will be expected to find resource savings of 15% through the better use of new technology and greater efficiency, while spending £900 million more on targeting tax evasion and fraud to help collect a missing £7 billion in tax revenues.
