Gen Sir David Richards: Economy biggest risk to UK

The biggest strategic risk facing the UK is economic not military, the head of the British armed forces has said.

General Sir David Richards said the UK's main effort must be the economy, as "no country can defend itself if bankrupt".

The eurozone crisis was of "huge importance" to military planners as well as the City, he said.

Despite defence cuts, Britain would remain "powerful relative to our allies", he added.
