In 2026, the real power in Iran now primarily rests with Mojtaba Khamenei, who was elected as the new Supreme Leader on March 8, 2026. This follows the assassination of his father, Ali Khamenei, and a brief interim period. While other bodies and individuals hold significant influence, the Supreme Leader’s role as commander-in-chief, policy setter, and ultimate arbiter of state affairs makes him the decisive force in the Iranian political landscape.
The position of Supreme Leader in Iran isn’t just titular; it’s the bedrock of the entire political system. His authority permeates every major decision, from national policy to day-to-day governance.
Mojtaba Khamenei’s Ascent to Power
Mojtaba Khamenei’s election marks a significant shift. The Assembly of Experts, as per constitutional mandate, conducted the election on March 8, 2026, following his father’s assassination. This move, while constitutionally sound on paper, has generated considerable internal debate regarding its implications for the Islamic Republic’s historical foundations.
The Supreme Leader’s Multifaceted Role
The Supreme Leader’s responsibilities are extensive and fundamental to the state’s functioning:
- Commander-in-Chief: This is not merely a ceremonial title. The Supreme Leader has direct control over all armed forces, including the Islamic Revolutionary Guard Corps (IRGC) and the regular army. This makes him the ultimate decider on matters of national security and defence.
- Supervision of Government Branches: He oversees the Judiciary, Legislature, and Executive branches, ensuring their alignment with the principles of the Islamic Republic. This oversight is subtle but pervasive, often exercised through appointments and indirect guidance.
- Key Appointments: The Supreme Leader appoints the Chief Justice, a move that immediately shapes the legal landscape of the country. This ensures that the judicial interpretation of laws aligns with his vision.
- Policy Architect: He sets both domestic and foreign policy, essentially charting the course for the nation. While various councils and ministries formulate details, the overarching direction comes from the Supreme Leader.
- Veto Power: Through the Guardian Council, which is largely appointed by or under the influence of the Supreme Leader, he holds effective veto power over parliamentary laws. This ensures that no legislation passes without tacit approval from the supreme office.
The Interim Period: A Glimpse into Transition Dynamics
The week-long interim period between Ali Khamenei’s assassination and Mojtaba Khamenei’s election offered a brief but informative look at how the Iranian state manages sudden leadership transitions.
The Interim Leadership Council
From March 1-8, 2026, an Interim Leadership Council took charge. This council consisted of three prominent figures:
- President Masoud Pezeshkian: As the head of the executive branch, his role would have focused on maintaining governmental functions and reassuring the public.
- Chief Justice Gholam-Hossein Mohseni-Eje’i: Representing the judiciary, he would have ensured legal continuity and stability during the sensitive period.
- Guardian Council member Alireza Arafi: His presence from the Guardian Council underscored the constitutional process for leadership selection and the clerical establishment’s role.
Ali Larijani’s Central Role
During this specific transition, one figure stood out for his management of day-to-day affairs:
- Ali Larijani, Secretary of the Supreme National Security Council: Larijani was instrumental in managing the regime’s daily operations and, crucially, security affairs. His long experience in various high-level positions, including former Speaker of Parliament, made him a natural choice to steer the country through such a fragile time. His role highlights the importance of the Supreme National Security Council (SNSC) in crisis management and coordination across different state organs. The SNSC is the key decision-making body for security and foreign policy, operating under the Supreme Leader’s ultimate authority.
Challenges to the New Leadership: Internal and External Pressures
Mojtaba Khamenei’s ascension to the Supreme Leadership is not without its significant hurdles, both from within Iran and from abroad.
Internal Legitimacy Concerns
The most potent internal challenge stems from a deep-seated ideological concern:
- Hereditary Succession Controversy: The election of Mojtaba Khamenei, the son of the previous Supreme Leader, has raised red flags for many in the regime. The 1979 revolution explicitly overthrew a monarchy, making any hint of dynastic succession a sensitive issue. Critics within the system fear that this could undermine the very ideological legitimacy of the Islamic Republic, eroding the revolutionary ideals of meritocracy and the rule of jurisprudence (Velayat-e Faqih) over lineage. This is a battle for the soul of the revolution, with some seeing it as a betrayal of its founding principles.
External Opposition and Threats
Beyond internal debates, Mojtaba Khamenei faces immediate threats from international actors:
- U.S. President Donald Trump’s Stance: President Trump has publicly declared Mojtaba Khamenei “an unacceptable choice” and, more concerningly, threatened military action if he doesn’t meet U.S. demands. This rhetoric immediately puts the new Supreme Leader under immense pressure, forcing him to navigate a precarious international landscape while consolidating power domestically. Such declarations signal a period of heightened tension and potential confrontation. The specifics of these “demands” have not been fully clarified, but historically they revolve around Iran’s nuclear program, ballistic missile development, and regional influence.
The Broader Power Brokers and Institutions
While the Supreme Leader is paramount, several other institutions and individuals contribute to the complex web of power in Iran. Their influence, though subordinate, is critical for the functioning and stability of the state.
The Islamic Revolutionary Guard Corps (IRGC)
The IRGC remains a formidable force, both militarily and economically:
- Military Arm: Beyond conventional defence, the IRGC is responsible for protecting the Islamic Revolution itself. Its Quds Force conducts extraterritorial operations, projecting Iranian influence abroad.
- Economic Reach: The IRGC controls vast swathes of the Iranian economy, from construction to telecommunications, giving it significant financial leverage and a vested interest in the status quo. Their commanders hold considerable sway, often acting as a parallel power structure to the conventional military and even certain government ministries. Their loyalty to the Supreme Leader is paramount.
The Guardian Council
This twelve-member body is a crucial gatekeeper of the Islamic Republic:
- Vetting Power: It vets all parliamentary candidates and presidential hopefuls, ensuring only those loyal to the system and the Supreme Leader can run for office. This significantly shapes the political playing field.
- Legislative Oversight: It reviews all legislation passed by the Majlis (parliament) to ensure compliance with Islamic law and the constitution. Their approval is necessary for any law to be enacted. Six members are clerics appointed by the Supreme Leader, and the other six are jurists nominated by the Chief Justice and approved by the Majlis.
The Assembly of Experts
This deliberative body holds symbolic and constitutional importance:
- Electing and Overseeing the Supreme Leader: As demonstrated by Mojtaba Khamenei’s election, this body is constitutionally tasked with electing a new Supreme Leader and, theoretically, overseeing his performance. However, in practice, their oversight capabilities are limited. Members are elected by popular vote, but candidates are first vetted by the Guardian Council.
The President and the Executive Branch
The President, as head of the executive branch, manages the day-to-day administration of the country, yet remains subordinate to the Supreme Leader:
- Masoud Pezeshkian: Currently serving as President, his role involves implementing policies, managing the government bureaucracy, and representing Iran on the international stage. While he holds a powerful position within the executive, his major policy decisions are ultimately subject to the Supreme Leader’s approval. The presidency is a significant platform, but not the ultimate locus of power.
Current Diplomatic Posture: Tactical Manoeuvring
| Position | Official | Power Level |
|---|---|---|
| Supreme Leader | Ayatollah Ali Khamenei | Highest |
| President | Ebrahim Raisi | High |
| Parliament Speaker | Mohammad Bagher Ghalibaf | Medium |
| Chief Justice | Ebrahim Raisi | High |
| Commander-in-Chief of Armed Forces | Ayatollah Ali Khamenei | Highest |
Iran’s current diplomatic engagements, particularly with the U.S. and Israel, should be viewed through the lens of the recent leadership transition.
- Tactical Positioning: Negotiations and public statements regarding relations with the U.S. and Israel are primarily tactical. They serve to gauge the new Supreme Leader’s stance, test the waters, and project an image of continuity or strength during a vulnerable period.
- Not Strategic Shifts: These engagements are less about fundamental shifts in strategic policy and more about short-term positioning. The core tenets of Iran’s foreign policy, driven by anti-Western sentiments and support for regional allies, are unlikely to change overnight. The new leadership will need time to consolidate power before embarking on significant strategic realignments. Any perceived flexibility or rigidity in diplomatic overtures is likely a function of internal dynamics as Mojtaba Khamenei establishes his authority.
In essence, Iran’s leadership structure in 2026 is anchored by the new Supreme Leader, Mojtaba Khamenei. While various institutions and individuals wield influence, their power remains circumscribed by the Supreme Leader’s authority. The coming months will be crucial as he consolidates his position amidst internal legitimacy concerns and external pressures, shaping the trajectory of the Islamic Republic for the foreseeable future.
