Son of assassinated Ayatollah Khamenei chosen as Iran’s new supreme leader, state media confirms

Iran’s Assembly of Experts named Mojtaba Hosseini Khamenei as the country’s third supreme leader on Sunday, 8 March 2026, according to reports from IRIB state television and the Fars, Tasnim and ISNA news agencies. Mojtaba Khamenei is the second son of Ayatollah Ali Khamenei, who was killed in United States and Israeli strikes on Tehran on 28 February 2026, becoming the first supreme leader of the Islamic Republic of Iran to die by assassination. The appointment is only the second time in the 47-year history of the Islamic Republic that the Assembly of Experts has been required to exercise its constitutional authority to select a new supreme leader. The first such transition occurred in 1989, when Ali Khamenei was chosen to succeed the republic’s founder, Ayatollah Ruhollah Khomeini.

What is the Assembly of Experts and how does Iran’s constitutional succession process determine the selection of a new supreme leader?

The Assembly of Experts is an 88-member body of Shia clerics constitutionally mandated under the Islamic Republic of Iran to select and, in principle, supervise the country’s supreme leader. Its sixth session, elected in 2024, is scheduled to sit until 2032. Under Article 111 of the Iranian constitution, the assembly is required to convene and select a new leader whenever the incumbent is no longer able to perform constitutional duties. In a statement circulated on Iranian state media, the assembly said Mojtaba Khamenei had been chosen on the basis of a decisive vote. The statement called on all Iranians, including scholars of religious seminaries and universities, to pledge allegiance to the new leader and to maintain national unity.

The Islamic Revolutionary Guard Corps declared its full obedience to Mojtaba Khamenei in a statement aired on state-affiliated IRIB television, describing him as a fully qualified jurist and the most knowledgeable figure in political and social matters. The Guard’s public declaration came within hours of the formal announcement and carried institutional weight given the central role the corps played in shaping the succession process itself.

Who is Mojtaba Khamenei and what role has he played within Iran’s political and security establishment before becoming supreme leader?

Mojtaba Hosseini Khamenei, 57 years old at the time of his appointment, is the second son of Ayatollah Ali Khamenei. While he has never held elected office, he spent years operating behind the scenes from within his father’s office, cultivating influence across the security establishment, particularly within the Islamic Revolutionary Guard Corps.

Mojtaba Khamenei was born in 1969 in the city of Mashhad and grew up during his father’s rise as a revolutionary cleric opposing the monarchy of Shah Mohammad Reza Pahlavi. He attended Alavi High School in Tehran, an institution known for educating members of Iran’s political and religious elite, graduating in 1987. After the death of Ayatollah Ruhollah Khomeini in 1989 and his father’s elevation to the position of supreme leader, Mojtaba Khamenei began formal clerical studies in Tehran, studying under his father as well as under Mahmoud Hashemi Shahroudi, who later served as Iran’s chief justice.

He holds the clerical rank of hojatoleslam, a mid-level designation below that of ayatollah. His father was not an ayatollah either when he became the country’s leader in 1989, and the law was amended to accommodate him. A similar constitutional adjustment may apply in Mojtaba Khamenei’s case. He has taught at religious seminaries in Qom, the center of Shia Islamic scholarship in Iran, for approximately eight years.

Mojtaba Khamenei began developing close ties within the Islamic Revolutionary Guard Corps from his younger years, when he served in the Habib Battalion of the corps during multiple operations in the Iran-Iraq War of the 1980s. Several of his comrades from that conflict went on to obtain leading posts in the security and intelligence apparatus of the nascent Islamic Republic. He later worked with former President Mahmoud Ahmadinejad on the 2005 and 2009 presidential campaigns. The 2009 contest prompted mass anti-government demonstrations, with protesters alleging vote rigging, and Mojtaba Khamenei was identified by multiple analysts as a key figure shaping the security crackdown that followed.

Mojtaba Khamenei has never given a public speech and is rarely seen in public settings. As there is limited public record of him, his political opinions are not fully known, but many analysts consider him a hardliner. He is under United States Treasury sanctions, imposed in 2019, on the grounds that he acted in an official capacity on behalf of his father despite holding no formal title or elected position.

How did the Islamic Revolutionary Guard Corps shape the emergency succession process and what divisions emerged within the Assembly of Experts?

Following the assassination of Ayatollah Ali Khamenei on 28 February 2026, governance of the Islamic Republic passed to a three-member interim leadership council comprising President Masoud Pezeshkian, Judiciary Chief Gholam-Hossein Mohseni-Ejei, and Guardian Council member Alireza Arafi. The Assembly of Experts held its first emergency session online on 3 March 2026. From early that day, Islamic Revolutionary Guard Corps commanders across different cities pressured assembly members to vote for Mojtaba Khamenei through in-person meetings and phone calls. Sources described the atmosphere inside the session as unnatural, with repeated contacts and sustained pressure on representatives continuing until minutes before the online meeting began.

United States and Israeli forces struck the Assembly of Experts building in the city of Qom after votes had been cast and before the count had been completed. Assembly leaders subsequently announced a second electoral session to be held on 5 March near the shrine of Fatima Masumeh in Qom. Eight members stated they would boycott the second session in protest at what they described as heavy pressure from the Revolutionary Guards to appoint Mojtaba Khamenei. The formal announcement was ultimately made on Sunday, 8 March 2026.

Significant internal opposition to the appointment emerged throughout the process. A group of opponents contacted the Assembly’s chairman and members of its leadership board, warning that declaring Mojtaba Khamenei supreme leader could raise public concerns about hereditary leadership and the Islamic Republic resembling a monarchy. One assembly member, speaking to Iran International, stated that Ayatollah Ali Khamenei had not been pleased with the idea of his son’s leadership and had never allowed the issue to be raised during his lifetime. A separate member argued that Mojtaba Khamenei lacked an established, public clerical and jurisprudential standing, and that his selection as the state’s supreme jurist, or Vali-ye Faqih, would lack religious legitimacy.

The Islamic Republic’s foundational ideology rests on the doctrine of velayat-e faqih, or guardianship of the jurist, which holds that the supreme leader must possess distinguished Islamic scholarship and political competence. The concerns raised within the assembly directly engaged that doctrinal standard. The 1989 transition that elevated Ali Khamenei had itself required a constitutional amendment removing the requirement that the leader hold the status of marja, the highest clerical ranking, in order to accommodate a candidate whose religious credentials fell short of traditional expectations.

What positions have the United States government and Israel taken on Mojtaba Khamenei’s appointment and the ongoing regional conflict?

United States President Donald Trump stated publicly before the announcement that Mojtaba Khamenei was unacceptable to him as a successor, describing him in remarks to Axios as a lightweight and stating that he believed he should be involved in the appointment process. Trump repeated that position in an ABC News interview, saying the new leader would not last long if Iranian leaders did not first receive his approval. The White House did not immediately respond to requests for comment following the formal announcement on Sunday.

Assembly of Experts member Hojjatoleslam Heidari Alekasir stated that a candidate had been picked based on Ayatollah Ali Khamenei’s advice that the supreme leader should be hated by the enemy rather than praised by them, adding that even the United States had mentioned the chosen successor’s name, a reference to Trump’s public statements about Mojtaba Khamenei in the days before the announcement.

The Israel Defense Forces warned on Sunday that any successor to Ayatollah Ali Khamenei would be considered a target. Israeli Defense Minister Israel Katz had previously warned that any new leader would become an unequivocal target for elimination and that Israel and the United States would work together to weaken the regime’s capabilities and create conditions for the Iranian people to replace it.

What does the appointment of Mojtaba Khamenei signal about the Islamic Revolutionary Guard Corps and Iran’s future political direction?

Mojtaba Khamenei’s selection as supreme leader signals that Iran’s ruling elite has chosen continuity over reform at a moment of extreme external pressure. His deep ties to the Islamic Revolutionary Guard Corps and the broader security apparatus suggest that the institutions driving Iran’s current military posture will retain strong influence in the next phase of leadership. The appointment also marks the first instance in the history of the Islamic Republic of a leadership transition that keeps power within the same family, a development multiple analysts have described as unprecedented.

His ascension is widely assessed as a consolidation of hardline factions within Iran’s ruling establishment, with analysts noting that it could indicate the government has little intention of pursuing negotiations or reaching a settlement in the short term. Mojtaba Khamenei has established relationships with Islamic Revolutionary Guard Corps commander Ahmad Vahidi, former IRGC intelligence chief Hossein Taeb, and Parliament Speaker Mohammad Bagher Ghalibaf.

The Islamic Republic was founded in 1979 on the explicit rejection of hereditary rule, following the revolution that overthrew the Pahlavi dynasty. The transfer of the supreme leadership from Ayatollah Ali Khamenei to his son Mojtaba Khamenei represents a structural departure from that founding principle, regardless of the formal constitutional process through which the appointment was made. The extent to which that contradiction affects the new supreme leader’s domestic legitimacy, particularly among clerical institutions and the broader Iranian public, remains one of the central unresolved questions in the aftermath of the appointment.
