Iran's Assembly of Experts named Mojtaba Khamenei as the country's new Supreme Leader on March 8, 2026, following the assassination of his father, Ayatollah Ali Khamenei, during joint United States-Israeli strikes on February 28. The appointment placed the 56-year-old cleric at the helm of the Islamic Republic during what observers described as the gravest crisis in the state's 47-year history.
Ali Khamenei, who had led Iran since 1989, was killed on the opening day of the US-Israeli military campaign against Iran. His death triggered an urgent leadership transition. Under Iran's constitution, the Assembly of Experts — an 88-member body of senior Shia clerics — holds sole authority to select a supreme leader.
The assembly convened in emergency session, largely online, on March 3, amid what multiple sources described as intense pressure from the Islamic Revolutionary Guard Corps (IRGC) to elect Mojtaba Khamenei. According to Iran International, IRGC commanders made repeated contacts with assembly members, pushing them to vote for the late leader's son. Some members reportedly objected to his lack of senior religious credentials — he holds the rank of hojatoleslam, a mid-level clerical rank — and to what critics described as a dynastic succession at odds with the Islamic Republic's founding ideology. A formal announcement was delayed until March 8.
Mojtaba Khamenei, born in 1969 and the second of the late leader's six children, had long wielded significant behind-the-scenes influence within Iran's political and security establishment. He built close ties to the IRGC from his years serving in its Habib Battalion during the Iran-Iraq War. US diplomatic cables have referred to him as "the power behind the robes," and the US Treasury sanctioned him in 2019 for advancing what it called his father's destabilising regional and domestic agenda. He has never held elected or publicly appointed office.
Immediately following the announcement, key Iranian institutions declared their support. Parliament Speaker Mohammad Bagher Ghalibaf called following the new supreme leader a "religious and national duty." The IRGC and armed forces pledged allegiance. The head of Iran's Expediency Council, Sadiq Larijani, endorsed the decision. Iranian President Masoud Pezeshkian called the appointment a "new era of dignity and strength" and a manifestation of national unity.
The international reaction was sharply divided. Russian President Vladimir Putin pledged "unwavering support" for Mojtaba Khamenei and expressed solidarity with Iran. China stated its opposition to any targeting of the new Supreme Leader. By contrast, US President Donald Trump, who had previously called Mojtaba "unacceptable" and a "lightweight," said Iran had made "a big mistake" and that the new leader would "not last long" without US approval. Israel's military declared any successor to Ali Khamenei a legitimate target and had threatened those participating in the selection process. Israel's Foreign Ministry labelled Mojtaba a "tyrant" who would continue what it described as the regime's brutality.
The selection marked the first time leadership of the Islamic Republic had passed from father to son — a point of contention within Iran given the state's explicit rejection of hereditary rule following the 1979 revolution. Reports indicated that Ali Khamenei himself had opposed his son's succession and had never permitted the matter to be raised during his lifetime.
As of March 8, the new Supreme Leader had not made a public statement. Iran had not signalled any immediate change in its strategic posture. The country remained under active military bombardment, and the leadership transition occurred with the conflict ongoing and no ceasefire in sight.
