To ask Her Majesty's Government what assessment they have made of the impact on the overall cohesion and effectiveness of NATO of the decision by the government of the United States, announced by the Under Secretary of Defense for Acquisition and Sustainment on 17 July, to remove Turkey from the F-35 fighter jet programme.

We are disappointed that Turkey has chosen to acquire the Russian S-400 air defence system. We will continue to discuss our concerns with Turkey as a valued NATO Ally and we remain committed to our strategic partnership. Our officials are in on going discussions with the F-35 Joint Programme Office and F-35 partners on the impact of Turkey's suspension from the F-35 programme.
