I share the hon. Gentleman’s frustration in this regard; I really, really do. But it is a sad fact that the tools in our toolbox are limited. What we can do is continue to make it clear to our interlocutors that this is not acceptable, right or proper, and that if Iran wants to restore its reputation, the early release of Nazanin and other dual nationals will go a very long way. It is the right thing to do, and I urge Iran to get on and do it.
