A helicopter carrying Iranian president Ebrahim Raisi, the country’s foreign minister and other officials crashed in the mountainous north-west reaches of Iran on Sunday 20 May, sparking a rescue operation in thick fog and driving rain. Raisi was a dedicated servant of Iran’s former supreme leader (the country’s highest authority), Ayatollah Ruhollah Khomeini. If a president dies in office, Iran’s constitution says that the first vice president takes over for a period of 50 days, with the approval of the supreme leader. A new presidential election is then held at the end of the interim period. Khamenei has confirmed that the first vice president, Mohammad Mokhber, will serve as the country’s acting president until elections are held. Will the death of president Ebrahim Raisi create more instability in the middle east ?
