The son of Ayatollah Ali Khamenei will become Iran’s next supreme leader, Iran’s semi-official Fars news agency announced, taking over after his father was killed in an attack by the US and Israel. Mojtaba Khamenei, 56, is the third person to lead the Islamic Republic and the first example of hereditary succession since the overthrow of the Pahlavi monarchy in the 1979 revolution. Iran’s Assembly of Experts elected the country’s next supreme leader in a “decisive vote,” according to Fars. The vote took place hours before the result was made public. Alex Vatanka, Middle East Institute Senior Fellow, joins Bloomberg Businessweek Daily to discuss Mojtaba Khamenei's ascent and what it means for Iran and global relations.
