Question to the Ministry of Defence:

To ask the Secretary of State for Defence, if it is government policy to cover overspends from the Defence Nuclear Enterprise budget from the wider Defence budget or from the Treasury reserve.

If an overspend within the Defence Nuclear Enterprise could not be managed within the ringfenced budget, then options to manage this within the wider Defence budget would be considered.

This is distinct from the Dreadnought programme for which HM Treasury hold a separate £10 billion contingency.
