Question to the Ministry of Defence:

To ask the Secretary of State for Defence, how many visits there have been to UK naval bases by foreign vessels capable of carrying nuclear weapons in each of the last ten years; which bases those vessels visited; and what nations those vessels originated from.

Many ships and submarines are theoretically capable of carrying nuclear weapons. Information regarding all visits to the UK by any nation's vessels over the last ten years could be provided only at disproportionate cost.
