Question to the Ministry of Defence:

To ask the Secretary of State for Defence, what progress his Department has made since the publication of the National Security Strategy and Strategic Defence and Security Review 2015 on the Trident renewal programme in November 2015; and if he will make a statement.

Further to the Strategic Defence and Security Review 2015, we are investing an additional £642 million in the design of the Successor submarine and ordering additional long-lead items, including for the fourth submarine. Negotiations with industry remain on-going on options for the subsequent investment stages and their scope, time and cost. The 2016 Annual Update to Parliament, which sets out progress on the Successor submarine programme, is planned for later this year.
