Her Majesty's Government why they propose to withdraw from membership of Euratom.
Euratom is a separate treaty-based community, it shares a common institutional framework with the EU, including a role for the Commission, the Courts of Justice of the European Union and the Council of Ministers. This makes Euratom and the EU uniquely legally joined. Therefore, on withdrawal from the EU, the UK will also be withdrawing from the Euratom Community. Article 106a of the Euratom Treaty makes Article 50 of the Treaty on the Functioning of the European Union applicable to the Euratom Community in identical terms.
Moving forward, the UK has enjoyed a successful relationship with Euratom for over 40 years and we want that relationship to continue. The shape of the UK’s future relationship with Euratom is subject to negotiations with the EU and our aim, throughout these negotiations, will be to maintain our mutually successful civil nuclear cooperation with Euratom and the rest of the world.
