A new United Nations treaty has entered into force, one which makes nuclear weapons illegal in the countries that sign it. The Treaty on the Prohibition of Nuclear Weapons (TPNW) officially entered international law on January 22nd.

59% of the UK public want the UK government to sign.

But shamefully the government refused to even participate in the treaty talks and even now it refuses to engage with this piece of international law. But that will not stop us from making progress. While we marked the entry into force of this treaty as a victory for grassroots campaigning and our anti-nuclear movement, the hard work re-starts now.  CND will continue to campaign for the UK to sign the TPNW, both by lobbying Parliamentarians and by strengthening the support for it at grassroots level. Get involved!

What can I do to support the campaign?

Talks not Bombs

  • Help us put pressure on the Foreign Secretary to attend the first meeting of the states parties of the TPNW. There are many ways for you to get involved – find out more.

Contact your MP 

  • Working with our partners in Parliament, CND is lobbying the British government to support the TPNW and work towards the global elimination of nuclear weapons. Use our lobby tool to ask your MP to sign EDM1072.

Sign the petition

  • The challenge now is to get the nuclear-armed states – including the UK – to sign the treaty. Sign our petition calling on the government to get rid of its nuclear weapons and support this treaty: we’ll be presenting your signatures at a later date.

  • CND has published a briefing on the treaty to explain its background and relevance. Click here to view on online version or you can order printed copies from the CND office. We also have leaflets and petitions available if you would like to organise a street stall or arrange to distribute these in your local area (contact information@cnduk.org).
  • CND organised a webinar with legal experts to discuss exactly what the implications of the treaty will be, both for the UK and for the international community. Watch it back here.

What will be the impact of the TPNW?

59 countries have ratified the agreement so far.

CND has launched a new report Nuclear Weapons are Banned! What does this mean for Britain?’ with some of our partner organisations which looks at this exact question.

The terms of the TPNW only apply to the countries that have signed and ratified the agreement. And although the nine nuclear-armed states currently state they will not support it, the treaty is a significant pointer towards changing international attitudes to nuclear weapons. Previous treaties prohibiting chemical and biological weapons helped to stigmatise them in the minds of the public. This is now taking place with nuclear weapons.

This historic agreement will no doubt generate international momentum towards global nuclear abolition. The treaty is a breakthrough in international disarmament efforts and will be of enormous support in achieving the goal that most of the world shares: that there is no place for these weapons of mass destruction.
