Iran Supreme Leader: Who Succeeds Khamenei

Few transitions of power in the Middle East have been as sudden and consequential as the one that took place in Iran in early 2026. When Ayatollah Ali Khamenei died in strikes on February 28, the race to replace the man who had led Iran for nearly four decades moved from behind closed doors to the global stage. Within days, his son Mojtaba Khamenei emerged as the frontrunner, and on March 8, the Assembly of Experts formally named him the country’s third Supreme Leader.

Current Supreme Leader: Mojtaba Khamenei (since 2026) ·

Number of Supreme Leaders: 3 ·
Date of Ali Khamenei’s death: February 28, 2026 ·

Five key facts about the leadership transition, drawn from official sources and verified reporting, help frame what changed and what stayed the same.

Who is the new supreme leader now in Iran?

Who is Mojtaba Khamenei?

• Mojtaba Khamenei is the son of Ayatollah Ali Khamenei, born around 1969–1970 (Reuters (news agency)).
• He has long been described as a shadowy figure in succession discussions, rarely appearing in public but closely involved in behind-the-scenes power brokering (BBC News (UK public broadcaster)).
• Reuters reported in June 2025 that Mojtaba was one of two leading succession candidates under discussion within Iran’s clerical elite (Reuters (news agency)).

How was he chosen?

• After Ali Khamenei’s death on February 28, 2026, Iran’s constitution triggered an interim succession mechanism under Article 111 (Al Jazeera (Qatari state-funded news network)).
• An interim council composed of the president, the head of the judiciary, and a senior cleric from the Guardian Council took temporary authority (CNN (US cable news network)).
• On March 8, 2026, the Assembly of Experts — an 88-member elected clerical body — voted to appoint Mojtaba Khamenei as the new Supreme Leader (The Guardian (UK daily newspaper)).

What is his background?

• Mojtaba Khamenei is described as closely adhering to his father’s hardline policies, particularly on foreign relations and internal security (Reuters (news agency)).
• He has been involved in mediating between Iran’s political factions and the security establishment for over a decade.
• His selection marks the first time a son has directly succeeded his father as Supreme Leader in Iran’s history.

The dynastic succession marks a significant departure from the Islamic Republic’s meritocratic ideals, raising questions about the regime’s legitimacy among its own population.

Who replaced Ayatollah Khomeini?

The first succession: Ali Khamenei

• Ayatollah Ruhollah Khomeini, the founder of the Islamic Republic of Iran, died on June 3, 1989, after a period of declining health (BBC News (UK public broadcaster)).
• His death was attributed to a heart attack, and he was succeeded by then-President Ali Khamenei, who was appointed by the Assembly of Experts.
• Khomeini is widely regarded as the architect of the 1979 Islamic Revolution and the founder of the velayat-e faqih system — the doctrine of rule by the Supreme Jurist.

How Khomeini’s death led to Khamenei’s rise

• Khomeini’s death created a power vacuum that was quickly filled by the Assembly of Experts, which selected Ali Khamenei — then a mid-ranking cleric — as the second Supreme Leader.
• Khamenei’s elevation was controversial at the time because he lacked the marja (grand ayatollah) status that many expected of the role.
• Over the next 37 years, Khamenei consolidated power, gradually transforming the office into the dominant institution in Iranian politics.

The implication: Khomeini’s succession set a precedent for rapid, elite-driven transitions — a pattern that repeated itself in 2026 with Mojtaba Khamenei’s appointment.

Who is more powerful in Iran, president or supreme leader?

Constitutional powers of the Supreme Leader

• The Supreme Leader is the head of state and the highest political and religious authority in Iran, as defined by the constitution.
• He serves as commander-in-chief of the armed forces and controls the Islamic Revolutionary Guard Corps (IRGC) and the regular military (Council on Foreign Relations (US think tank)).
• He appoints the head of the judiciary, the head of state media, and half of the Guardian Council members.
• He has the power to dismiss the president following a Supreme Court ruling or a parliamentary vote.

Powers of the President

• The president is the head of government, responsible for the day-to-day administration of the country.
• The president appoints the cabinet, but all ministers must be approved by the Supreme Leader.
• The president manages the budget and economic policy, but major strategic decisions — particularly on foreign policy and nuclear issues — require Supreme Leader approval.

Key differences

One way to compare the two roles: the president runs the country’s bureaucracy, but the Supreme Leader controls its direction.

This structural imbalance means that while Iran holds presidential elections, the ultimate direction of the country remains firmly in the hands of the Supreme Leader.

Is Ayatollah Khomeini dead?

When did Khomeini die?

• Ayatollah Ruhollah Khomeini died on June 3, 1989, at the age of 89.
• His death marked the end of the founding era of the Islamic Republic of Iran (Al Jazeera (Qatari state-funded news network)).

Cause of death

• Khomeini died of a heart attack after a period of illness.
• His funeral drew millions of mourners in Tehran, one of the largest public gatherings in human history.

Legacy

• Khomeini is considered the founder of the Islamic Republic and the intellectual father of the velayat-e faqih system.
• His legacy remains deeply polarizing: revered by conservative supporters of the regime, reviled by opposition groups and human rights advocates.
• The question of his popularity is itself contested — BBC News (UK public broadcaster) notes that while he mobilized millions during the revolution, his later years saw growing repression and the Iran-Iraq War’s devastating toll.

Who is next in line after Khamenei?

The succession process

• Under Iran’s constitution, the Assembly of Experts — an elected body of 88 clerics — is responsible for selecting the Supreme Leader (Carnegie Endowment for International Peace (Washington DC think tank)).
• The Assembly requires only a simple majority to appoint a new leader, meaning the process can move quickly when the political will exists (Al Jazeera (Qatari state-funded news network)).
• In the event of a vacancy, Article 111 of the constitution provides for a temporary three-member council composed of the president, the head of the judiciary, and a senior cleric from the Guardian Council (CNN (US cable news network)).

Potential candidates

• Before Ali Khamenei’s death, Reuters (news agency) reported that Mojtaba Khamenei was one of two leading candidates, with other clerical figures also under discussion.
• BBC News (UK public broadcaster) reported that former president Hassan Rouhani and former judiciary chief Ebrahim Raisi had also been discussed as possible successors in earlier years.
• The Guardian (UK daily newspaper) reported that the Assembly of Experts was evaluating six potential candidates in March 2026 before settling on Mojtaba.

Mojtaba Khamenei’s role

• Mojtaba Khamenei is now the Supreme Leader, meaning the question of “next in line” is deferred — but the same dynamics apply to his eventual successor.
• His consolidation of power will likely involve placing loyalists in key military and judiciary positions.
• The Council on Foreign Relations (US think tank) notes that the Supreme Leader’s authority depends not only on the constitution but on factional support within the clerical and security establishment.

The stability of Mojtaba Khamenei’s leadership will depend on his ability to maintain the coalition of clerics, generals, and technocrats that sustained his father’s 37-year rule.

Sources and perspectives

“Mojtaba Khamenei, the son of Iran’s Ayatollah Ali Khamenei, who was killed in US-Israeli strikes, has been chosen as his successor.”

— The Guardian (UK daily newspaper)

“Iran’s Assembly of Experts named Mojtaba Khamenei to replace his father as supreme leader.”

— The Jerusalem Post (Israeli daily newspaper)

“Even before the succession crisis, Reuters reported that Mojtaba Khamenei was one of two leading candidates under discussion.”

— Reuters (news agency)

“The Assembly of Experts is an elected body of 88 clerics. It requires only a simple majority to appoint the next supreme leader.”

— Carnegie Endowment for International Peace (Washington DC think tank)

The pattern across these reports is clear: the succession was swift, elite-driven, and ultimately dynastic. For Iran’s political system, the question is not whether Mojtaba Khamenei can command the same authority as his father — but whether the clerics, generals, and technocrats who helped his father rule for 37 years will transfer that loyalty to the son. For the people of Iran, the transition offers little immediate hope of change: the new leader is a hardliner who has spent his entire career in the shadow of the old one.

The transition to Mojtaba Khamenei as Iran’s new supreme leader is covered in a detailed report on the succession.
