The Integrated Review increased our nuclear weapons stockpile ceiling from no more than 225 to no more than 260. None of the United Kingdom's nuclear weapons are designed for tactical use during conflict. The nuclear deterrent exists to deter the most extreme threats to our national security and way of life, which cannot be deterred by other means.
