Question to the Ministry of Defence:

To ask Her Majesty's Government what discussions they have had, either (1) unilaterally, or (2) with NATO partners, with the government of Turkey about the future of the S-400 missile defence system which that country acquired from Russia in 2019.

As a close ally of Turkey, the UK has expressed its disappointment on numerous occasions, both publicly and privately since 2019, that Turkey purchased the S-400 system. As one of Turkey's closest international partners, the UK has emphasised repeatedly that this system poses a threat to NATO systems. We continue to encourage Turkey to recommit to find a way through this impasse with the US and other Allies.
