Arms Exports

I share your distress regarding the plight of so many innocent people around the world who are suffering as a result of conflicts through no fault of their own. I do not believe, however, that a blanket arms embargo would resolve the problem you identify.
The Government takes its defence export responsibilities extremely seriously and operates one of the most robust export control regimes in the world. All export licence applications are rigorously assessed on a case-by-case basis against the Consolidated EU and National Arms Export Licensing Criteria. 
These strict criteria take account of all prevailing circumstances at the time of application and includes human rights and international humanitarian law considerations. The Government does not issue export licences where there is a clear risk that the goods might be used for internal repression, in the commission of a serious violation of international humanitarian law, or where the export would provoke or prolong conflict.
I am confident that by adhering to the Consolidated EU and National Arms Export Licensing Criteria, the Government will continue to ensure that UK arms exports are not used for internal repression, violating international humanitarian law, or for provoking or prolonging conflict.
