Strategic Defence and Security Review 2010

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. 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. 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. The final amount was a 7.7% reduction over four years.
