Question to the Foreign, Commonwealth & Development Office:

To ask the Secretary of State for Foreign, Commonwealth and Development Affairs, what recent assessment he has made of the potential merits of instituting snapback sanctions on Iran in accordance with the terms of the Joint Comprehensive Plan of Action nuclear deal.

We have always been clear: Iran's nuclear escalation is unacceptable. It is threatening international peace and security and undermining the global non-proliferation system.

A viable deal was put on the table in March which would have returned Iran to full compliance with its JCPoA commitments and returned the US to the deal.

Iran refused to seize a critical diplomatic opportunity to conclude the deal with continued demands beyond the scope of the JCPoA.

We are considering next steps with our international partners.
