Iranian opposition leader Mirhossein Mousavi has been returned home from hospital, where he was admitted yesterday after complaining of heart problems.
Supporters say he had tests and angiogram procedures before he was escorted home back to his house arrest. The former prime minister has been cut off from the outside world for the last 18 months after calling on Iranians to emulate their Arab brothers and sisters and take to the streets in February 2011.
In 2009 he stood as a reformist candidate against President Ahmedinjad. Critics then called for his arrest and execution, but the regime has preferred to isolate and sideline him.
