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.

Police spending will fall by 4% each year of the spending settlement, with the aim of avoiding any reduction in the visibility and availability of police on the streets.

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.
