Question

To ask the Prime Minister, under which criteria the Government would consider it justified to launch (a) a pre-emptive nuclear attack on another independent state or states using the Trident nuclear weapons system based in Scotland and (b) a retaliatory nuclear attack on another independent state or states using the Trident nuclear weapons systems based in Scotland.

The UK has long been clear that we would only consider using our nuclear weapons in the most extreme circumstances of self-defence.
