Ministers act to head off revolt over membership of European nuclear regulator

Government considering 'associate membership' of group that governs movement of radioactive material across Europe

The government is drawing up plans to replicate the benefits of remaining a member of the Euratom treaty, which governs the movement of nuclear materials across Europe, in the face of a growing rebellion of Conservative MPs.

The Guardian understands that one option being considered is an "associate membership", similar to that held by Switzerland, or paying money to an international agency to set up an independent arrangement.
