My right hon. Friend is absolutely right. Of course we will be fully plugged in and, indeed, a driving force in the international effort to make sure we get the right answers in terms of the investigation. This point is even stronger now that the Government of Iran have accepted at least a measure of responsibility, but it is crucial that the investigation is fully independent and has an international component so that people can feel confidence in the outcome and the answers. We will work with all our international partners on all the issues he raises, and I certainly want to see justice for the incredible number of people who are still mourning and grieving this terrible loss.
