 So to Iran, millions of people have been voting in the country's presidential election. The choice is between a tightly controlled list of four candidates close to the supreme leader, Ayatollah Ali Khamenei. The former heart surgeon, Massoud Pezeshkian, is the only reformist on the ballot, and he's previously criticised Iran's morality police. The elections are taking place following the death of Ebrahim Raisi, who was killed in a helicopter crash last month.
