The Ceremony and the Succession: Inside Iran's Assembly of Leadership Experts
On a Thursday afternoon in Tehran, a man stood before a gathered assembly and read a message. The scene, carried by Iran's state-affiliated news agencies on 29 May 2026, had the familiar cadence of regime ceremonial life: hymns, portraits of the founder, the language of martyrdom. Ayatollah Mohammad Reza Mahdi Kermani, Chairman of the Assembly of Leadership Experts, addressed a commemoration ceremony for what Iranian state media described as the martyrs of the family of Imam — the family of Ayatollah Ruhollah Khomeini, founder of the Islamic Republic. The agencies, Mehr News, Tasnim, and Fars, each carried the same dispatch in Persian and, in Tasnim's case, in English translation, a routine multiplication of official text across the state's media architecture.
For most observers, this would register as a brief item in a regional newsletter — a ceremonial paragraph, quickly forgotten. But the body Kermani chairs is not a ceremonial body. The Assembly of Leadership Experts is, on paper, one of the most powerful institutions in the Islamic Republic. Its eighty-eight clerics are elected by popular vote for eight-year terms. Its sole constitutional function is to select a Supreme Leader — and to supervise that leader's performance, and, if conditions are met, to remove one. The assembly meets in plenary session several times a year. The rest of the time, its chairman occupies a role that commands enormous internal power while remaining largely invisible to external analysis.
That contrast — between the quiet, consequential authority of the institution and the public-facing performance of commemorative ceremony — is the key to reading Iranian political life in 2026. The Supreme Leader, Ayatollah Ali Khamenei, is eighty-five years old. He has held the position since 1989, when Khomeini died and the assembly elected his successor from a shortlist of senior clerics. Khamenei was not the obvious favourite at the time. He was younger, less prominent than other candidates, and his appointment surprised some analysts who expected a more senior figure to be chosen. The assembly, in that moment, demonstrated a capacity for collective decision-making that proved decisive. The choice, whatever internal debates produced it, held. The Islamic Republic transitioned without visible rupture.
That is the institutional memory the assembly carries — and the burden it bears in any future succession scenario.
The Constitutional Architecture of Succession
Iran's constitution, amended in 1989 to restructure the leadership model after Khomeini's death, assigns the Assembly of Leadership Experts a cluster of responsibilities that go well beyond the act of election itself. The assembly is required to monitor the Supreme Leader's performance, to investigate complaints about his decisions, and to convene if a leader becomes incapacitated through illness or political crisis. In extremis, it can declare the Supreme Leader incapable of fulfilling his duties and trigger a new election. The constitution does not precisely define the threshold for incapacitation — that ambiguity has always been understood internally, a feature rather than a bug of a system designed to manage elite consensus rather than rule by written procedure.
The assembly's current composition reflects the clerical establishment that has governed since the revolution's early decades. Its eighty-eight members are a cross-section of the Islamic Republic's clerical elite: senior clerics, mid-career jurists, regional religious figures. Many have served multiple terms. The body includes figures associated with different currents within the Iranian political system — pragmatists, hardliners, quietists — but the institutional logic of the assembly tends to discourage open factional division. A public schism over succession would delegitimise the very body tasked with managing the transition.
Kermani himself has occupied the chairmanship since 2019, elected by his fellow members in a vote that received public coverage inside Iran. His background is in Islamic jurisprudence and he has served in various judicial and clerical capacities across the post-revolutionary period. He is not a figure of the first rank of public visibility — the chairmanship does not require one — but he is trusted within the clerical establishment, which matters more in this context than public recognition.
The ceremony of 29 May involved Kermani reading a message from the assembly to a commemorative audience — a ritual act of political theology rather than a statement of institutional decision. The content of the message, carried by Iranian state media, invoked the language of sacrifice, continuity, and revolutionary memory that has characterised Iranian official discourse since 1979. The specific martyrs commemorated were members of Khomeini's family killed in a bombing in 1981 — an event that, in the mythology of the Islamic Republic, occupies the same structural place that assassination mythology occupies in other revolutionary states: proof of the regime's enemies, justification for its security apparatus, evidence that the founding generation paid with blood for the republic that followed.
What the 1981 Bombing Left Behind
The 1981 bombing in Tehran — which killed dozens, including the Iranian president, prime minister, and several cabinet ministers — was one of the most destabilising events in the early Islamic Republic. TheMujahedin-e Khalq, an opposition group that had initially supported the revolution before turning against it, was blamed for the attack. The bombing decapitated the government's civilian leadership in a single afternoon and forced a rapid reconstitution of the state apparatus under Khomeini's direct supervision.
The long-term consequence was a consolidation of security-state logic inside Iran — a permanent rationale for vigilance against internal enemies, an argument against opening political space, a justification for the intelligence apparatus that has shaped Iranian politics ever since. The event also created a cohort of martyred leaders whose families remain connected to the regime's inner circle. The commemoration Kermani addressed on 29 May was, in part, an act of intergenerational continuity — the current generation of clerical leaders honouring the generation that paid the price of state-building.
This is not incidental. The Islamic Republic has always managed its founding mythology with care, using commemorative ceremony to reinforce the bond between the state and its earliest supporters. The families of the martyred remain embedded in the political class. Their descendants occupy positions across the clerical and security establishment. The ceremony was, in this sense, also a display of institutional inheritance — a demonstration that the generation now managing the state considers itself custodian of a debt.
The Succession Question, Set Aside for Now
The structural question that most exercises external analysts — what happens when Khamenei dies — is genuinely open, and genuinely uncertain, and deliberately kept unanswerable by the system itself. The assembly has the authority to act. It has a defined constitutional pathway. It has institutional memory of managing a transition in 1989. But the specific variables of any future moment — the state of Iranian foreign policy, the balance of internal factions, the health of the economy, the relationship with external powers — will shape what the assembly does in ways that cannot be predicted in advance.
What is observable is the preparation. The assembly has, in recent years, conducted its meetings with a regularity that suggests institutional seriousness rather than pro forma compliance. Its membership includes figures considered possible candidates in a future succession — senior clerics with the jurisprudential credentials the constitution demands, men who have spent decades in the Islamic Republic's governing structures. None of them is publicly discussed as a successor because the moment has not arrived and because discussing it openly would be politically awkward. But the assembly itself is, in part, a pre-selection mechanism: its members know each other's work, their temperaments, their positions on the key questions of clerical governance.
Khamenei's health is not publicly discussed in Iranian state media — it rarely is — and external reporting on this question is necessarily speculative. What is known is that he is eighty-five, has held the leadership since 1989, and has managed Iran through wars, sanctions, protests, and a series of regional crises. The system is designed to function through the leader, not around him, which means any incapacitation — however defined — would create a structural gap that the assembly would need to fill quickly.
The Stakes: What a Transition Would Mean
A Supreme Leader succession in Iran would be consequential in ways that extend well beyond the person of the successor. The office carries authority over the military, the judiciary, the intelligence services, the state media, and the foreign policy apparatus. It shapes Iran's posture toward the United States, toward Israel, toward the Gulf states, toward the nuclear programme, toward the network of regional proxies that constitutes Tehran's influence across the Middle East. A leader who arrives at the office with a different calculation of risks and interests — or who arrives under conditions of internal crisis that force compromise — changes the calculus of every actor in the region and beyond.
The assembly's composition matters here. Its current membership is not a random cross-section — it reflects the clerical politics of four decades. Hardliners are represented. Pragmatists are represented. Men who have spent their careers inside the Islamic Republic's governing structures and who have a material stake in its continuity are well represented. The institutional logic of the assembly is conservative in the structural sense: it is designed to preserve the system, not to reform it. That does not mean the next Supreme Leader will be identical to Khamenei — personal style, health, and the specific pressures of the moment shape how any leader exercises power. But the assembly's probable direction in any succession is toward continuity with the existing framework, not toward rupture.
The ceremony Kermani presided over on 29 May is, in this context, a reminder of the distance between the surface of Iranian political life and its deeper structures. The language of martyrdom, the hymns, the commemorative posture — these serve a real function in a system that derives legitimacy from revolutionary origin rather than from electoral mandate. They reinforce the bond between the governing class and the founding myth. They demonstrate continuity with the dead. But they also perform the invisible work of institutional maintenance — reminding the audience, and the broader clerical class, that the regime has a history, a logic, and a set of organs designed to outlast any individual holder of power.
The Assembly of Leadership Experts is one of those organs. For most of the year, it is invisible. But its existence, and its mandate, is the structural guarantee that the Islamic Republic has prepared — however imperfectly — for the one succession that matters most.
