Former foreign secretary Jack Straw has said that rising security threats present an "overwhelming case" for reviewing the 2010 Strategic Defence and Security Review (SDSR).
The Labour MP said events in Algeria, Mali and elsewhere highlighted weaknesses in the SDSR, which has led to cuts in numbers in the Armed Forces.
But answering the query at Prime Minister's Questions, David Cameron insisted Britain was focused on targeting its defence budget in the most effective ways possible.
