Iran’s supreme leader Ayatollah Ali Khamenei has assigned vice president Mohammad Mokhber to assume interim duties after the death of President Ebrahim Raisi in a helicopter crash a day earlier.

“In accordance with Article 131 of the constitution, Mokhber is in charge of leading the executive branch,” said Khamenei in a statement, adding that Mokhber will be required to work with the heads of legislative and judicial to prepare for presidential elections “within a maximum period of 50 days”.
