The UK government has announced it will increase the number of nuclear warheads in its arsenal for the first time since the Cold War.


Protest is a fundamental right in our society and CND is making our opposition to this announcement clear.

The Integrated Review

The integrated review of security, defence, development and foreign policy published on March 16th included a 40% increase in the stockpile. The UK currently has around 200 warheads, but had previously announced a cap of 180 by the mid-2020s. It will now increase this cap to 260 warheads.

Shamefully the government also announced it will stop publishing information on the number of warheads and missiles in operation, making scrutiny – including of the out of control costs of Britain’s nuclear weapons system – even more difficult. In addition, the integrated review included a change in use posture – the government will now consider using nuclear weapons in response to non-nuclear threats, including ‘emerging technologies’ which could mean a cyber-attack.

We don’t want to increase the potential of using nuclear weapons. And we don’t want any more of them. In fact, we don’t want any. And polling published earlier this year showed that 77% of the public agree and want a total ban on all nuclear weapons globally.

The real threats facing us today are painfully obvious to see – we should be using our resources to deal with actual problems such as climate change and the pandemic. We should not be spending billions of pounds on weapons of mass destruction when investment is urgently needed in our NHS, education system and green jobs. It’s notable that the government’s priority isn’t to give nurses a well-deserved pay-rise, but to get more nuclear weapons.

It is being asked across Parliament and the media if this is even legal. The answer is a resounding No. Increasing Britain’s nuclear arsenal contravenes our legal obligations under the nuclear Non-Proliferation Treaty, which Britain ratified in 1970. The Treaty requires countries that have nuclear weapons to disarm, and those that don’t have them not to get them. There is no way in which increasing a nuclear arsenal is legitimate under the Treaty.

This development is hugely provocative on the global stage: the first step in a new nuclear arms race.
