Could I not continue, because I have just been interrupted? I will perhaps give way to the noble Lord in a minute.
I turn to Amendment 2, tabled by the noble Lord, Lord Warner. He refers to the supply to the United Kingdom of medical radioisotopes and their use and
disposal, so far as this depends on UK membership of Euratom. My understanding is that it does not depend on UK membership of Euratom. Sixty per cent of the United Kingdom’s isotope supply comes from the EU and 40% from non-EU countries—predominantly South Africa, I think. Both are imported into the UK under fast-track procedures, and there seems no reason why that should change, whether or not we are a member of Euratom.
It is clearly essential that we avoid a cliff edge in this field, and for that reason, I look forward to hearing what the Minister has to say about the Government’s intention to avoid one. Clearly, something which replicates the effect of continued membership of Euratom during a transition period would be the easiest way to achieve that, because it will not be possible in the time available before March 2019 to negotiate and have ratified by their legislatures the four essential nuclear co-operation agreements with the United States, Australia, Japan and Canada that are our minimum requirement.
I am now happy to give way to the noble Lord.
