To ask the Secretary of State for Defence what analyses he has undertaken on the nature and origin of the component parts of improvised explosive devices found in Afghanistan.

In order to protect UK forces, analysis and assessment of the threat posed by improvised explosive devices (IEDs) in Afghanistan continues to receive the highest priority. We routinely analyse IED incidents that occur in Afghanistan, in close consultation with our ISAF partners. I cannot comment further on this type of work as its disclosure would or would be likely to prejudice the capability, effectiveness or security of the armed forces.
