To ask Her Majesty’s Government whether the decision to proceed with the building of four replacement Trident submarines will require parliamentary approval; and if so, whether they plan to seek such parliamentary approval at the same time as, or before, the Main Gate decision is made.
15 June 2015
This Government was elected on a mandate to renew Trident and provide continuous at sea deterrence by replacing the Vanguard-class submarines with a fleet of four Successor submarines. Parliament has already debated the vote twice on the issue, on 14 March 2007 and again on 20 January 2015. A further debate is planned during this Parliament.
