Question to the Ministry of Defence:

To ask the Secretary of State for Defence, what assessment his Department has made of the consequences for the viability of the Successor submarine programme of the conclusions of the Infrastructure and Projects Authority's assessment of that programme.

The Infrastructure and Projects Authority's assessment of the Successor submarine programme accords with our own. That is why we have established a new Director General Nuclear sponsor organisation and will set up a new submarine delivery body, as set out in the Strategic Defence and Security Review 2015. The assessment recognises the complexity and scale of delivering the most advanced submarines ever commissioned by the Royal Navy.
