Iran's ambassador-designate to Lebanon, Mohammad Reza Sheibani, is actively defying a government expulsion order, relying on political cover from Hezbollah and Parliament Speaker Nabih Berri to remain in Beirut. The standoff exposes severe fractures within the Lebanese state as authorities attempt to curb Iranian influence amid the ongoing regional war.

The source explicitly noted that the envoy's decision to stay is "in accordance with the wishes of the speaker of parliament Nabih Berri and of Hezbollah," effectively using the country's parallel power structures to override state authority.

The timeline of the rupture maps a rapid deterioration in Beirut-Tehran relations. On March 24, Lebanese Foreign Minister Youssef Raggi initiated the formal expulsion process. Raggi instructed the Ministry of Foreign Affairs' Secretary-General to summon Tufiq Samadi Khoshkhou, the Iranian Chargé d'Affaires in Lebanon. During this summons, the ministry formally withdrew the agrément for Sheibani, declared him persona non grata, and established the strict Sunday, March 29 deadline for his departure. The ministry cited violations of diplomatic norms and interference in internal politics as the primary drivers for the expulsion.

Sheibani is now actively leveraging the political and physical cover provided by the Hezbollah-Amal alliance to bypass Raggi's declaration. Following the March 24 summons, Hezbollah publicly condemned the expulsion, while ministers affiliated with both Hezbollah and Berri's Amal movement boycotted subsequent cabinet sessions in protest. By anchoring his presence to Berri—a foundational figure in the Lebanese state apparatus—and the armed deterrence of Hezbollah, Sheibani has exposed the severe limitations of Prime Minister Nawaf Salam's government in enforcing its own sovereign mandates. What remains unclear is whether Lebanese state security forces will attempt any physical enforcement of the persona non grata order, or if the diplomatic paralysis will simply hold.

• Iranian ambassador-designate Mohammad Reza Sheibani ignored the March 29 deadline to leave Lebanon, with AFP sources confirming his refusal to exit.
• Lebanese Foreign Minister Youssef Raggi initiated the expulsion on March 24 by summoning the Iranian Chargé d'Affaires to declare Sheibani persona non grata.
• Sheibani is relying on the political protection of Hezbollah and Parliament Speaker Nabih Berri to defy the government's mandate.

The expulsion order against Iranian ambassador-designate Mohammad Reza Sheibani has triggered an immediate institutional freeze in Beirut [1.9]. Shiite ministers aligned with Hezbollah and Parliament Speaker Nabih Berri’s Amal movement launched a coordinated boycott of cabinet sessions this week. The walkout effectively paralyzes executive functions, weaponizing Lebanon's sectarian power-sharing system to shield Tehran’s diplomatic anchor. Verification of parliamentary attendance logs confirms the Hezbollah-Amal bloc is withholding participation to stall further state action against Iranian interests.

Opposing this boycott is a government coalition led by Prime Minister Nawaf Salam and President Joseph Aoun. The Salam-Aoun bloc is advancing an executive push to outlaw Hezbollah’s military operations and dismantle the local infrastructure of the Islamic Revolutionary Guard Corps (IRGC). For the administration, enforcing Sheibani’s departure is a foundational test of sovereign control following the devastating 2024-2025 regional conflict. Official statements from the Prime Minister's office indicate a strict policy against parallel military structures, though the exact timeline for dismantling IRGC networks remains unclear.

The standoff lays bare the severe limits of state enforcement. While the foreign ministry formally declared Sheibani persona non grata and set a March 29 departure deadline, executing that order is another matter. The Lebanese Armed Forces and internal security apparatus lack the political consensus—and the physical monopoly on force—to deport an envoy protected by Hezbollah cadres. Authorities cannot physically extract Sheibani without risking direct armed confrontation in the capital. The government is currently trapped between its legal decrees and the tactical reality on the ground, leaving the cabinet unable to convene and the ambassador entrenched.

• Shiite ministers from Hezbollah and the Amal movement are boycotting cabinet sessions, halting executive functions to protect the Iranian envoy [1.9].
• Prime Minister Nawaf Salam and President Joseph Aoun are leading a government push to outlaw Hezbollah's military wing and expel the IRGC.
• State security forces lack the operational capacity to physically deport Sheibani without triggering an armed domestic conflict.

Hostilities erupted on March 2 when Hezbollah launched rocket barrages into Israel following the assassination of Iranian Supreme Leader Ali Khamenei. As Israeli airstrikes and ground operations dismantle southern Lebanon and target Beirut, Prime Minister Nawaf Salam’s government is attempting to sever the Lebanese state from Tehran's military calculus. Foreign Minister Youssef Raggi’s mandate for Sheibani to leave by March 29 represents a sharp diplomatic rupture, signaling Beirut's urgent effort to reassert sovereignty amid mass displacement and mounting casualties.

The core of Beirut’s confrontation with Tehran lies in the operational command of the current conflict. Prime Minister Salam has openly accused the Islamic Revolutionary Guard Corps (IRGC) of managing Hezbollah’s strikes from Lebanese territory, stating plainly that the war was imposed on the country. Moving beyond rhetoric, the Lebanese cabinet issued directives banning Hezbollah’s military activities and ordering the arrest of IRGC personnel operating locally. Salam noted it is not Lebanon's duty to avenge Khamenei. Declaring Sheibani persona non grata was intended as the diplomatic enforcement of this boundary, penalizing Tehran for what Lebanese officials describe as a blatant violation of diplomatic norms and state security.

Sheibani’s active defiance, however, lays bare the structural paralysis of the Lebanese state. Relying on political cover from Hezbollah and Parliament Speaker Nabih Berri, the envoy remains in Beirut, effectively neutralizing the Foreign Ministry's decree. This institutional fracture carries immediate, severe security implications. If state security apparatuses cannot compel the departure of a single foreign diplomat, the government's broader mandates—disarming a militant faction or extracting entrenched IRGC commanders—are tactically unfeasible. Lebanon is currently navigating a catastrophic conflict officially opposed by its own government, yet dictated by parallel power structures that the state is powerless to dismantle.
