I welcome the clarity of my right hon. Friend’s statement today and I look forward to the publication tomorrow of the defence and security industrial strategy alongside it, which will provide, I hope, a degree of coherence that will be very welcome to all those involved in supporting our armed forces.
In light of the necessary decision to proceed with upgrading the warhead for the strategic deterrent, can my right hon. Friend explain to the House the rationale for increasing the number of warheads during the transition from one system to the next? Will the cost in developing the strategic deterrent absorb any of the welcome £6.6 billion R&D programme that has been announced?
