Important Facts The Assembly of Experts is the constitutional mechanism for leadership transition. Its members are elected by popular vote, though candidates are vetted by the Guardian Council. The death of Khamenei on 1 March 2026 triggered a formal transition process, with interim officials assuming key responsibilities while the Assembly convenes. Iran’s constitution mandates that the Supreme Leader be a “marja‑e‑taqlid” (source of emulation) and possess the requisite religious and political stature. The urgency expressed by Khatami reflects concerns over internal stability and external pressure, especially after the recent strikes that damaged the Assembly’s infrastructure.
