Question to the Ministry of Defence:

To ask the Secretary of State for Defence, with reference to the Strategic Defence and Security Review, which improvements in performance in the delivery of the Successor submarine programme (a) have been achieved and (b) he expects to be achieved in the next 12 months.

We are working closely with all of our key suppliers to ensure that they make improvements, where required, to deliver both the capability and the capacity we need to successfully deliver the Successor programme. This work builds on the efficiencies and improvements already made as part of initiatives such as the Submarine Enterprise Performance Programme.

Discussions with our key suppliers are ongoing and it would not be appropriate for the Ministry of Defence to discuss this work publicly for commercial reasons.
