The JCPoA agreed with Iran in 2015 envisaged a "Transition Day" eight years later, when remaining ballistic missile and nuclear-related sanctions on Iran would be lifted. But Britain, France and Germany will now transfer UN sanctions on Iran that are due to be lifted next month into domestic law, while Britain and the EU will retain existing sanctions, Britain's Foreign office said in a statement. The crux of the JCPoA pact, which Iran made with Britain, China, France, Germany, Russia and the U.S., limited Tehran’s nuclear programme making it harder for it to get fissile material for a bomb in return for relief from economic sanctions. We stand ready to reverse our decision, should Iran fully implement its JCPoA commitments," the E3 said, referring to a mechanism that would immediately restore all UN sanctions against Iran.
