Question to the Ministry of Defence:

To ask the Secretary of State for Defence, what assessment he has made of the date by which (a) doctrine and (b) training will need to have changed by in order to reflect the option of an air-launched tactical nuclear weapon.

Joining the NATO nuclear mission does not change the UK's Nuclear doctrine. Both the UK and NATO view the fundamental purposes of nuclear weapons to preserve peace, deter aggression, and prevent coercion.

UK training plans will also be informed by our NATO Allies already contributing to the mission. Further work is underway.
