Diplomatic relations after the Iran nuclear deal

With the US Congress just a week away from voting on the Iran nuclear deal – a historic deal that has already improved relations between Iran and the West – LSE Associate Professor of International History, Dr Roham Alvandi, spoke to BBC News about UK Foreign Secretary Philip Hammond’s visit to Iran. The Foreign Secretary was in Iran to re-open Britain’s embassy, which was shut in 2011 when it was stormed by violent protesters.
