Question to the Foreign, Commonwealth & Development Office:

To ask the Secretary of State for Foreign, Commonwealth and Development Affairs, what assessment his Department has made of the accuracy of recent reports that Iran is concealing the scale of its nuclear programme.

We remain committed to preserving the Joint Comprehensive Plan of Action (JCPoA). It remains the best, and currently the only, way to monitor and constrain Iran's nuclear programme.

Iran's continued systematic non-compliance with its JCPoA commitments is undermining the non-proliferation benefits of the deal and jeopardising our efforts to preserve it. The UK has repeatedly made clear in public and in private, both bilaterally and with the governments of France and Germany (as E3), that Iran must change its approach and co-operate fully with the International Atomic Energy Agency (IAEA). In his call with President Rouhani on 10 March, the Prime Minister stressed that while the UK remains committed to making the JCPoA a success, Iran must stop all nuclear activity that breaches the terms of the deal and come back into compliance.

We continue to work with the parties to the JCPoA and the new US Administration to find a diplomatic way forward that realises the benefits of the deal, and call upon Iran not to take any further steps which violate its JCPoA commitments and make a return to mutual compliance harder to achieve
