The Campaign for Nuclear Disarmament (CND) has sharply criticized the UK's latest defence spending review, arguing that measures like the build-up of nuclear-powered submarines and the procurement of nuclear-capable F-35 jets dangerously escalate nuclear proliferation and militarism. CND contends that such strategies not only increase the risk of nuclear conflict but also divert essential public funds away from welfare, health, education, and climate initiatives, calling instead for a shift towards a demilitarized, human-centric defence strategy.

Campaign for Nuclear Disarmament (CND) published a campaign page titled 'A nuclear-free world' urging for an international ban on nuclear weapons and calling on the UK to join the treaty. The initiative underscores the risks of nuclear armament in exacerbating global conflicts and potential authoritarian militarism.

Throughout 2025, the Campaign for Nuclear Disarmament (CND) is organizing a national tour of nuclear bases across Britain to protest the replacement of the Trident nuclear system and argue for redirecting government spending toward social services such as homes, education, and health.

The Campaign for Nuclear Disarmament (CND) has condemned the government's rushed parliamentary process to permanently extend the US-UK Mutual Defence Agreement. In response, CND is mobilizing a protest at RAF Lakenheath on November 2, 2024, to oppose not only the treaty’s railroading but also the prospect of US nuclear weapons returning to Britain.

Campaign for Nuclear Disarmament (CND) is actively lobbying the British government to sign and ratify the Treaty on the Prohibition of Nuclear Weapons and oppose the replacement of Trident. This effort aligns with global movements advocating for nuclear disarmament and a reduction in authoritarian military policies.

CND welcomed a report from the Nuclear Education Trust, which advocated for government investment in economic diversification in Barrow and reducing reliance on BAE Systems, as expressed by General Secretary Kate Hudson. This endorsement aligns with CND's anti-militaristic and progressive principles.

On December 16, 2009, CND Chair Kate Hudson publicly refuted allegations that the Campaign for Nuclear Disarmament had ever received financial support from the former Soviet Union, labeling the claims as baseless and unsubstantiated. The statement emphasized transparency, personal responsibility for accuracy, and a commitment to open political debate over its anti-nuclear positions.

A scholarly chapter details how the Campaign for Nuclear Disarmament used propaganda and parody during the 1980s to undermine British government nuclear weapons and civil defence policies, presenting an alternative, progressive political narrative against state-endorsed defence measures.

The Campaign for Nuclear Disarmament (CND), founded in 1957, held its first major public meeting on 17 February 1958. This event marked the beginning of its decades-long campaign advocating unilateral nuclear disarmament and opposing militarism and nuclear armament. By organizing mass public demonstrations and promoting peace, CND laid a foundational role in progressive, anti-authoritarian activism in the UK.
