In the wake of the assassination of Iran’s Supreme Leader Ali Khamenei, the Islamic Republic has embarked on a significant constitutional transition that marks the end of nearly 37 years under his leadership. This sudden change has thrust the nation into a critical juncture, raising profound questions about the future direction of its political system and governance.
Immediately following Khamenei’s death, Iranian authorities swiftly initiated constitutional protocols designed to maintain governmental stability during this uncertain period. On Sunday, an interim leadership council was officially formed to oversee state affairs until a permanent successor is appointed. This temporary body is tasked with ensuring continuity in the highest echelons of power, preventing any vacuum that could destabilize the country.
the framework set by Iran’s constitution, the interim council is composed of three key figures: the current president, the head of the judiciary, and a clerical member of the Guardian Council chosen by the Expediency Council. The Expediency Council itself is a powerful institution responsible for advising the supreme leader and arbitrating disputes between the parliament and supervisory bodies, underscoring the intricate balance of power within Iran’s political system.
The newly formed council includes reformist President Masoud Pezeshkian and the hardline Chief Justice Gholamhossein Mohseni-Ejei. Together, they temporarily wield the extensive powers traditionally held by the supreme leader, although their authority is explicitly limited to this transitional phase. This arrangement reflects an effort to maintain a semblance of unity between reformist and conservative factions during a period of potential volatility.
Meanwhile, the responsibility of selecting a new supreme leader falls to the Assembly of Experts, an 88-member body consisting solely of Shiite clerics. This assembly, elected every eight years by popular vote but with candidates vetted by the Guardian Council, is constitutionally mandated to appoint the successor “as soon as possible.” However, the Guardian Council’s stringent control over candidate eligibility has historically shaped the political landscape, as evidenced by its recent disqualification of former President Hassan Rouhani from running for the Assembly in March 2024.
Deliberations within the Assembly of Experts are traditionally conducted behind closed doors, leaving much of the succession process shrouded in secrecy. Despite this opacity, speculation about potential successors has intensified, with particular attention on Mojtaba Khamenei, the 56-year-old son of the late supreme leader. Although Mojtaba holds no formal government position, his possible elevation has sparked debate and concern. Critics warn that a dynastic transfer of power could provoke resistance from both opposition groups and influential elements within the regime who are wary of undermining the revolutionary ideals established in 1979.
Previously, hardline President Ebrahim Raisi was widely regarded as the frontrunner to succeed Khamenei. However, Raisi’s unexpected death in a helicopter crash in May 2024 dramatically altered the succession landscape, opening the field to new contenders and complicating the political calculus within Iran’s ruling elite.
This transition represents only the second time in the Islamic Republic’s history that a supreme leader has been replaced. Khamenei himself assumed the role in 1989 after the death of Ruhollah Khomeini, the founding figure of the Islamic Republic. The gravity of this moment cannot be overstated, as the new leadership will shape Iran’s ideological and strategic trajectory for years to come.
Adding to the urgency of this leadership change are escalating regional tensions. Just last year, Iran and Israel engaged in a 12-day conflict that heightened security concerns and underscored the importance of stable governance. Khamenei’s role as supreme leader encompassed ultimate control over Iran’s political and religious institutions, including command of the armed forces and oversight of the Islamic Revolutionary Guard Corps (IRGC). The IRGC, designated a terrorist organization by the United States in 2019, has been central to Iran’s regional influence through its leadership of the so-called “axis of resistance” and its substantial economic power within the country.
With the interim council now operational, all eyes are on the Assembly of Experts and the speed with which it will move to appoint a permanent successor. The decision will not only determine the future leadership of Iran but also influence the broader geopolitical dynamics of the Middle East. As the nation navigates this pivotal moment, the world watches closely, aware that the outcome will resonate far beyond Iran’s borders.
