Why we must save vital nuclear treaty with our allies in the EU

talented scientists; those working in cancer medicine are seeking urgent assurances from the Government; and there is uncertainty over the UK’s plans for nuclear power, not least at Hinkley Point.

We believe there is an opportunity for a rethink. Both our parties are committed to implementing the result of the referendum on EU membership, even though we both campaigned to remain. But this is not about EU membership. Our co-operation on nuclear issues predates the EU. Whatever people were voting for last June, it certainly wasn’t to junk 60 years of co-operation in this area with our friends and allies.

The Government’s justification for this decision needs to be carefully scrutinised. We are told that because the Euratom treaty shares some institutions with the EU, legally we must leave. But this is disputed by eminent lawyers.

It appears the problem with continued membership comes down to the involvement of the European Court of Justice in its oversight.

There appears never to have been an ECJ case involving the UK and Euratom. But it does require us to continue to allow the free movement of nuclear scientists. For this reason, it appears, the Government has determined the UK should leave. This makes no sense. The UK must remain a beacon for global talent after Brexit – indeed, that is the Government’s stated aim.

It is not too late to change course. There are indications that a rethink would be welcomed with open arms by the Euratom member states.

Next week, Parliament will debate this issue for the first time. We hope ministers are listening to the legitimate concerns that are being raised across parties, and will agree that the common sense thing to do is for the UK to remain in Euratom.
