Tehran is witnessing a historic and delicate shift in its political landscape after the assassination of Supreme Leader Ali Khamenei, who had been the face of the Islamic Republic for nearly 37 years. This unprecedented event has triggered a constitutional process aimed at ensuring the continuity of governance while setting the stage for a consequential leadership transition. The country now stands at a crossroads, grappling with both internal power dynamics and external pressures that could define its future trajectory.
In the immediate aftermath of Khamenei’s death, Iranian authorities swiftly activated constitutional protocols designed to maintain stability during this critical period. On Sunday, an interim leadership council was officially formed to temporarily oversee the affairs of state until the Assembly of Experts selects a permanent successor. This move reflects the constitutional mechanism intended to prevent any power vacuum that might destabilize the nation amid rising uncertainties.
The interim council is composed of three key figures as mandated by Iran’s constitution: the current president, the head of the judiciary, and a clerical member of the Guardian Council appointed by the Expediency Council. This tripartite body is entrusted with wielding the supreme leader’s extensive powers on a provisional basis. Notably, reformist President Masoud Pezeshkian and hardline Chief Justice Gholamhossein Mohseni-Ejei are among those now holding this temporary authority, highlighting the complex interplay of political factions during this transitional phase.
Meanwhile, the responsibility to appoint the next supreme leader falls to the Assembly of Experts, an 88-member body consisting solely of Shiite clerics. These clerics are elected by the public every eight years, although their candidacies must first receive approval from the Guardian Council, which has a history of disqualifying candidates deemed unsuitable. This vetting process underscores the tightly controlled nature of Iran’s political system, where power is concentrated within a select religious elite.
In recent months, the Guardian Council’s influence was evident when it barred former President Hassan Rouhani from contesting a seat in the Assembly of Experts, signaling the body’s firm grip on shaping the country’s leadership. The Assembly’s deliberations on the new supreme leader are traditionally conducted behind closed doors, leaving much of the succession process shrouded in secrecy and speculation.
Among the names circulating as potential successors, Mojtaba Khamenei, the 56-year-old son of the late supreme leader, has attracted significant attention despite holding no formal government position. His candidacy raises concerns about the possibility of dynastic succession, a concept that could provoke resistance from both regime opponents and factions within the political establishment wary of consolidating power within a single family. This tension reflects broader anxieties about the future direction of a system born out of the 1979 Islamic Revolution.
Previously, hardline President Ebrahim Raisi was widely regarded as the frontrunner to succeed Khamenei. However, his unexpected death in a helicopter crash in May 2024 dramatically altered the succession landscape, opening the field to new contenders and increasing uncertainty about the regime’s next steps. This transition marks only the second time Iran has undergone a change in its supreme leadership since the Islamic Republic’s inception, with Khamenei himself having succeeded Ruhollah Khomeini in 1989.
The stakes of this leadership change are further heightened by ongoing regional instability. Just last year, Iran and Israel engaged in a 12-day conflict that underscored the volatility of the Middle East and the critical importance of steady leadership in Tehran. Khamenei’s role extended beyond political governance; he was the ultimate authority over Iran’s armed forces and the Islamic Revolutionary Guard Corps (IRGC), a powerful military and economic entity central to Iran’s regional influence. The IRGC, designated a terrorist organization by the United States since 2019, has been instrumental in supporting Iran’s network of allied groups across the Middle East, known as the “axis of resistance.”
With the interim council now managing the state’s affairs, all eyes are on the Assembly of Experts and the timeline for appointing the new supreme leader. The decision will not only determine the immediate political direction of Iran but also shape its domestic policies and regional posture for years to come. As the nation navigates this pivotal moment, the balance between reformist and hardline elements within the leadership will be crucial in defining the future of the Islamic Republic.
