US-UK Mutual Defence AgreementMutual Defence Agreement • July 18th, 2018
A sixty year-old nuclear agreement between the United Kingdom and United States of America was last renewed in 2014 with no parliamentary debate or vote. The British public and parliamentarians initially found out about that latest extension and ratification of the Mutual Defence Agreement (MDA) when President Obama informed the United States Congress. CND maintains that the terms of the MDA are in contravention of the UK’s legal commitments as signatories to the nuclear Non- Proliferation Treaty (NPT).

The Agreement between the UK and the USA for Cooperation in the Uses of Atomic Energy for Mutual Defence Purposes 1958, also known as the Mutual Defence Agreement (MDA), allows the USA and the UK to exchange nuclear materials, technology and information. It was the result of an amendment to post-War US non-proliferation law, which exempted allies that had made substantial progress in developing nuclear weapons from the general ban on exchanges that might lead to nuclear proliferation.

REFORM NOT RENEWALMutual Defence Agreement • June 5th, 2014
The US-UK Mutual Defence Agreement (MDA) was first signed in 1958 to allow the exchange of classified nuclear information, nuclear weapon technology, and scientific expertise, with the aim of helping both nations to develop their nuclear weapons systems. The Agreement – a formal treaty between the two nations - has been amended a number of times over its 56 year history, and most recently has been renewed on a regular ten year cycle to allow arrangements for the transfer of special nuclear materials and non-nuclear components of nuclear weapons to be extended.
