It is a pleasure to serve under your chairmanship, Sir Charles. I am grateful to the hon. Member for Hampstead and Kilburn (Tulip Siddiq) for securing the debate and for her tireless work in supporting Nazanin and Richard and in championing this issue. Although there have been times when we have disagreed, it is absolutely right that I put on the record our respect for the hon. Lady's passion. The hon. Member for Lewisham East (Janet Daby) mentioned her support for the family of her constituent, and right hon. and hon. Members have spoken about the work that they have done to support family members of those in Iran. Other Members were unable to attend the debate because of ministerial duties—I think particularly of my hon. Friend the Member for North East Hampshire (Mr Jayawardena), who speaks to me regularly about the situation and who is the constituency MP for some of the members of Richard and Nazanin's family. Like all Members of the House and everyone in the country, I have huge sympathy for the families of those who are incarcerated in Iran. The Government will continue to do everything we can to resolve the situation in which they find themselves through no fault of their own. The ongoing suffering that Iran is inflicting on British dual nationals such as Anousheh Ashouri and Morad Tahbaz is deeply distressing and rightly elicits very strong feelings from hon. Members of different parties. I cannot overstate the fact that the Government share that frustration and are unwavering in our commitment to resolve this issue. We have made it clear to the Iranian Government at every stage that we expect Iran to release all British dual nationals and allow them to return home to their families. In today's debate, we are focusing primarily on Nazanin, Richard and Gabriella. The UK Government continue to work tirelessly to secure Nazanin's full, permanent release and ability to return home to her family. As right hon. and hon. Members are aware, Nazanin was released on furlough into the care of her parents in Tehran in 2020, but the Iranian system has refused to let her return home and has not left her alone during the period of furlough. The Government have kept up our campaign of pressure on the Iranian authorities throughout this time, and we will not relent until she is fully and permanently released. At every stage since Nazanin was detained, the UK Government have carefully considered and assiduously pursued the courses of action that we have assessed offer the best opportunity for resolving this case. We have not pursued any course of action that we believe would be counterproductive to the release and return home of those in incarceration. In March 2019, my right hon. Friend the Member for South West Surrey (Jeremy Hunt) afforded diplomatic protection to Mrs Zaghari-Ratcliffe. This formally raised it to a state-to-state issue. At that time, he also recognised that that was unlikely to yield immediate results, in part because Iran does not recognise dual national status. Unfortunately, his prediction at the time seems to have been proven right. Since then, this Government have continued to take further action where we judge it will help to secure full and permanent release. We constantly review what other steps are possible, and we weigh up all the diplomatic and legal tools available to secure her release. However, I have made the point already that—I suspect in large part because Iran does not recognise dual nationality and therefore does not recognise our authority to speak on this issue—that has proven to be of limited success in the instance of Nazanin. We will continue to hold the Iranian Government to account for their treatment of the British dual nationals in incarceration, including Anousheh Ashouri and Morad Tahbaz. I assure the House that the Government remain committed to doing whatever we can to secure their release and will continue to work and make representations at every opportunity on their behalf. I remind all Members that it was the Iranian Government who arrested these British dual nationals. It was the Iranian Government who applied these bogus charges against them. It was the Iranian Government who hold these people in incarceration and prevent them from coming home. It is the Iranian Government who are wholly and solely responsible for the appalling circumstances that these people find themselves in. The British Government will continue to work tirelessly to secure their release and return home. I assure everyone in the House that that will remain our priority until they are released and are able to return home.
