Question to the Ministry of Defence:

To ask His Majesty's Government what consideration they are giving to securing the full independence of the UK's nuclear deterrent.

I can assure the noble Lord that the United Kingdom’s nuclear deterrent is completely operationally independent. Only the Prime Minister can authorise the firing of our nuclear weapons, even if they are to be employed as part of a NATO response.

The UK has a longstanding, close relationship with the US on all defence nuclear issues, which has endured through many changes of Government in our two nations. Our extant long-term arrangements under the 1958 Mutual Defense Agreement and the 1963 Polaris Sales Agreement (as amended in 1982 for Trident) provide for co-operation and collaboration which has been, and continues to be, of considerable mutual benefit to both nations.
