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

Penny Mordaunt, Secretary of State for Defence, responded “It is UK and NATO policy to neither confirm nor deny the presence of nuclear weapons onboard specific ships or submarines at any particular place or time, for the purposes of safeguarding national security and international relations.”
