Today, on the International Day for the Total Elimination of Nuclear Weapons, CND is launching its new campaign against Britain’s reckless nuclear expansion that risks us all.

To start, we have secured a legal opinion showing that the government’s expansion of its nuclear weapons capability is in clear breach of international law.

The new legal opinion, which has been published today, finds that Britain's purchase of 12 F-35A nuclear-capable fighter jets is in violation of its commitments under Article VI of the nuclear Non-Proliferation Treaty (NPT). The article states: that, ‘[e]ach of the Parties to the Treaty undertakes to pursue negotiations in good faith on effective measures relating to cessation of the nuclear arms race at an early date and to nuclear disarmament, and on a treaty on general and complete disarmament under strict and effective international control.’

In their joint opinion, international law experts Professor Christine Chinkin and Dr Louise Arimatsu, argue: “[t]he decision of the UK to purchase F-35a fighter jets rather than any other model is precisely because the aircraft can ‘deliver both conventional and nuclear weapons’ and thereby enable the RAF to reacquire ‘a nuclear role for the first time since 1998.’ Reinstating a nuclear role for the RAF represents a reversal of the UK’s long-term commitment to nuclear disarmament, including under the NPT.”

Lobby your MP: Stop British nukes jets!

Despite the far-reaching consequences of this nuclear expansion, the government has failed to allow for any debate or vote on the decision. This is totally unacceptable. So we’re urging MPs and peers to help secure a debate. We need to make sure this is an issue that won’t go away for the government. It is just the first step in a public campaign that calls for a change in direction, away from warmongering and nuclear expansion, towards diplomacy, global cooperation and genuine security for all.
