Members of Britain's shadow cabinet have criticised Labour leader Jeremy Corbyn for saying he would never press the ‘nuclear button’.

We believe his stance is the only possible option. Giving the order to fire nuclear weapons would cause mass devastation on a global scale, and a global nuclear war could even end humanity altogether.

It is absurd to treat someone who says he won’t use these terrible weapons as some sort of ‘extremist’. Trident makes us less safe, not more.

We would never press the button. We support Jeremy Corbyn’s decision and call on all of Labour’s senior members to do likewise.
