I disagree with my hon. Friend. I think the JCPOA has been an important attempt at least to try to bring stability to the region. The region was not stable before the JCPOA was negotiated between 2005 and 2015. We believe not just that the deal is based on trust about Iran’s intentions, but that it provides for rigorous verification and monitoring that allows the International Atomic Energy Agency access to Iran’s nuclear programme, and in return we want to see some economic sanctions being lifted. I understand the concerns my hon. Friend has raised, but it would be wrong to think we could either walk away from this plan of action or feel that it is open for fundamental renegotiation, and I do not think that would be practical diplomatic politics either.
