Question to the Foreign, Commonwealth & Development Office:

To ask Her Majesty’s Government what estimates have been made of the quantities of western-manufactured weapons currently held by ISIL; and when and how they were obtained.

It is very difficult to estimate the quantities of weapons held by the Islamic State of Iraq and the Levant (ISIL) and their sourcing. It is likely that ISIL has obtained its weaponry from a variety of sources, and it is extremely difficult to estimate with any degree of useful accuracy how many specifically western manufactured weapons are currently held by ISIL (as opposed to western designs copied by other countries). We remain deeply concerned about the ability of terrorist groups in Iraq and Syria to acquire weapons and commit atrocities.
