Question to the Foreign, Commonwealth & Development Office:

To ask the Secretary of State for Foreign and Commonwealth Affairs, what representations he has made to NATO on the Turkish Government's procurement of the Russian S-400 Missile Defence System.

​We have raised our concerns with the NATO Secretary General and discussed this issue with a number of Allies. The Secretary General has made clear that while defence equipment procurement decisions are for nations, it is very important that our respective systems are interoperable. We share this view.
