My hon. Friend will know that, along with our E3 colleagues, we have triggered the dispute resolution mechanism for the JCPOA on the nuclear side. It has always been the case that the JCPOA did not encompass the wider destabilising activities in which Iran engages in the region through militias and proxies, and we have always been open and willing, and indeed pressing, to try to incorporate a bigger agreement. But it is also right to say that until there is scope for that wider agreement, what we have is the JCPOA, which provides the vehicle for some kind of restraint on Iran, although I accept that it has been eroded because of systemic non-compliance. We would be reluctant to move to something bigger until it is in place, and should not lose sight of what the JCPOA adds.
