Question to the Foreign, Commonwealth & Development Office:

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

​We have repeatedly raised our concerns about the proposed Turkish purchase of S-400 missiles, at Ministerial and official level. Turkey is a valued NATO ally, on the front line of some of the UK and the Alliance's most difficult security challenges. Defence equipment procurement decisions are for nations, but all NATO allies have committed to reducing their dependence on Russian-sourced legacy military equipment. The proposed purchase would pose real challenges for the interoperability of NATO systems.
