If the right hon. Gentleman will forgive me, I want to make a little bit of progress, and I will then give way to him.
I draw hon. Members’ attention to the explanatory notes to the Bill, which set out the application of the Bill to Euratom. The Bill also gives the Prime Minister the power to start the process to leave Euratom. The Bill makes it clear that in invoking article 50, we will be leaving Euratom, the agency established by treaty to ensure co-operation on nuclear matters, as well as leaving the European Union. This is because, although Euratom was established in a treaty separate from the EU agreements and treaties, it uses the same institutions as the European Union, including the European Court of Justice. The European Union (Amendment) Act 2008 makes it clear that in UK law membership of the European Union includes Euratom. That is why article 50 applies to both the European Union and to Euratom.
