We have left no stone unturned. I went to Teheran on 19 November, and I have given Nazanin diplomatic protection. I have changed the travel advice to try to prevent this from happening to other dual nationals, and the Minister for the Middle East, my right hon. Friend Dr Murrison, raised the matter in Teheran at the end of last week. We are doing absolutely everything we can, because this is an appalling injustice.
