My Lords, once again I thank noble Lords for an excellent debate on this important issue. I will respond to the point raised by most people who spoke—certainly the noble Lords, Lord Hunt, Lord Warner, Lord Teverson, Lord Carlile, Lord Liddle and Lord Adonis—about the reasons for leaving Euratom.
The Euratom treaty is legally distinct from the European Union treaty but it has the same membership, which includes all 28 member states, and makes use of the same institutions. There are no precedents for a non-European Union member state being a member of Euratom.
Noble Lords will recall that the decision to leave Euratom formed part of both Houses’ consideration of the European Union (Notification of Withdrawal) Bill, which is now of course an Act. Noble Lords spoke at that time about the unique nature of the relationship between the separate treaties of the European Union and Euratom. As the European Union and Euratom are uniquely legally joined, when we formally notified our intention to leave the European Union we also commenced the process for leaving Euratom.
