Iran Leadership Succession Begins After Death of Supreme Leader Ali Khamenei

The death of Iran’s Supreme Leader, Ali Khamenei, after nearly 37 years in power has triggered a constitutional succession process and raised significant questions about Iran’s political future, regional posture, and internal stability.
Under Iran’s constitution, a temporary leadership structure was established the morning following his reported assassination.
Temporary Leadership Council Assumes Authority
Iran on Sunday formed an interim leadership council to carry out the duties of the supreme leader until a successor is appointed.
The council consists of the sitting president, the head of the judiciary, and a clerical member of the Guardian Council selected by the Expediency Council, a body that advises the supreme leader and resolves disputes between parliament and oversight institutions.
Reformist President Masoud Pezeshkian and judiciary chief Gholamhossein Mohseni Ejei are among those tasked with temporarily assuming leadership responsibilities.
Assembly of Experts to Select New Supreme Leader
While the interim council governs in the short term, Iran’s constitution requires the 88-member Assembly of Experts to appoint a new supreme leader “as soon as possible.”
The Assembly is composed entirely of Shiite clerics elected every eight years, though candidates must first be approved by the Guardian Council, Iran’s constitutional oversight body. The Guardian Council has historically disqualified candidates across various elections, including former President Hassan Rouhani, who was barred from running for the Assembly of Experts in 2024.
The succession process typically unfolds behind closed doors, making it difficult to assess potential outcomes or leading candidates.
Possible Contenders and Political Sensitivities
Before his death in a 2024 helicopter crash, former President Ebrahim Raisi had been widely viewed as a potential successor to Khamenei.
Attention has since turned to Mojtaba Khamenei, a cleric and the late leader’s son. Although he has not held formal government office, he is regarded by some analysts as a possible contender. However, a direct father-to-son succession could prove controversial within Iran’s political establishment and among segments of the public, particularly given the Islamic Republic’s origins in the 1979 revolution that overthrew the monarchy of Mohammad Reza Pahlavi.
A Rare Leadership Transition
This marks only the second transfer of power in the office of supreme leader since the 1979 Islamic Revolution. In 1989, Grand Ayatollah Ruhollah Khomeini died after leading the revolution and presiding over Iran during its eight-year war with Iraq. Khamenei succeeded him later that year.
The current transition follows a period of heightened regional tensions, including a 12-day conflict between Israel and Iran in June 2025.
Powers of the Supreme Leader
The supreme leader occupies the highest authority within Iran’s political system, which blends republican institutions with clerical oversight. The position holds ultimate decision-making power over state policy, the armed forces, the judiciary, and key security institutions.
The supreme leader also serves as commander-in-chief of Iran’s military and the Islamic Revolutionary Guard Corps (IRGC). The United States designated the IRGC a foreign terrorist organization in 2019. The force plays a central role in Iran’s regional strategy, including its network of allied groups often referred to as the “Axis of Resistance.”
The coming weeks are expected to be critical for Iran’s internal political balance, regional alliances, and broader Middle East stability.
