Iran's Supreme Leader: Constitutional Role and Powers
The position of Supreme Leader (Rahbar) is the highest political authority in Iran under the 1979 Islamic Republic constitution. The Supreme Leader commands the armed forces (including the Islamic Revolutionary Guard Corps, IRGC), appoints judiciary heads, controls state media, and has ultimate veto over all state decisions. The Guardian Council — which vets all election candidates — reports to the Supreme Leader, making the position the apex of the entire political system. Iran has had only two supreme leaders: Ayatollah Ruhollah Khomeini (1979-1989) and Ali Khamenei (1989-2026).
- Supreme Leader commands the IRGC, Basij militia, regular armed forces
- Appoints 6 of 12 Guardian Council members, all judiciary heads, and IRGC commander
- Khamenei held the position from 1989 until his death on 28 February 2026
- Article 111 of Iran's constitution requires the Assembly of Experts to immediately convene and appoint a successor
Connection to this news: Trump's demand for a say in the selection directly challenges Iran's constitutional sovereignty; it has no legal standing under Iranian law but signals US intent to shape the post-war Iranian political order.
Assembly of Experts: Iran's Supreme Leader Selection Body
The Assembly of Experts (Majles-e Khobregan) is an 88-member body of Islamic jurists (Mujtahids) directly elected by Iranian voters every eight years. It is constitutionally tasked with selecting, monitoring, and if necessary dismissing the Supreme Leader. Candidates for the Assembly must be vetted by the Guardian Council, which screens them for ideological conformity. In practice the Assembly has historically been a ceremonial endorsement body rather than a genuinely deliberative one. The 2026 succession is the first contested selection since 1989, when Khamenei was chosen as a compromise candidate after Khomeini's death.
- 88 members, elected every 8 years by popular vote
- Candidates must be approved by the Guardian Council (itself appointed partly by the Supreme Leader)
- Selection criteria (Article 109): qualified Islamic jurist, just, pious, politically aware, capable of leadership
- Israel bombed the Assembly's Qom facility in March 2026 to disrupt the selection vote
Connection to this news: The Assembly's ability to function independently is under severe external pressure — from Israeli military action, US diplomatic interference, and internal factional divisions over Mojtaba Khamenei's candidacy.
IRGC and the Succession Power Struggle
The Islamic Revolutionary Guard Corps (IRGC) is a parallel military force established in 1979 to protect the Islamic Revolution, distinct from the regular Iranian army. It controls significant economic enterprises, runs the Quds Force (external operations), and has deep influence over Iran's political elite. Mojtaba Khamenei, the frontrunner for succession, has close ties to the IRGC — making his selection a potential consolidation of IRGC power in Iran. The IRGC was designated a Foreign Terrorist Organisation by the US in 2019.
- IRGC established 1979; commands ~120,000 personnel plus Basij paramilitary
- Controls Quds Force (external proxy operations in Lebanon, Iraq, Yemen, Syria)
- Designated Foreign Terrorist Organisation by US in 2019
- Mojtaba Khamenei: 56 years old, hardline cleric, no prior public office, strong IRGC ties
Connection to this news: The succession outcome will determine whether Iran's post-war political direction tilts toward IRGC hardliners (under Mojtaba) or opens to a more reform-oriented figure — a choice with major implications for regional stability and US-Iran relations.
