The Strategic Defence and Security Review 2010 was announced by the formed Conservative-Liberal Democrat coalition government of the United Kingdom in May 2010, and published on 19 October 2010.[1] The previous major review of UK defence strategy was the Strategic Defence Review, published in 1998, and updated in 2003 by the Delivering Security in a Changing World white paper.
As well as wanting an updated security policy, both the Conservatives and Liberal Democrats wanted the £38 billion overspend in the Ministry of Defence (MoD) procurement budget addressed.[2] With the government committed to reducing the national budget deficit, the Treasury asked the MoD to draw up options for a 10–20% real-terms cut in its budget.[3] The final amount was a 7.7% reduction over four years.[4]
