The Joint Comprehensive Plan of Action (JCPoA) is the best, and currently only, way to monitor and constrain Iran's nuclear programme. But 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. 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 are particularly concerned by Iran's announcement on 16 April that it has started uranium enrichment up to 60% using advanced centrifuges. As the E3 said in a statement on 14 April, the production of highly enriched uranium constitutes an important step in the production of a nuclear weapon. Iran has no credible civilian need for enrichment at this level.
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.
