In the wake of the death of Supreme Leader Ayatollah Ali Khamenei, Ali Larijani has emerged as a key power broker in Iran, with plans to establish an interim leadership council. This council will include the president, the head of the judiciary, and a jurist from the Guardian Council to manage state affairs until a new supreme leader is elected. "An interim leadership council will soon be formed," Larijani stated, indicating that the council would be operational as soon as possible, according to Reuters and India Times.

Larijani's response following Khamenei’s assassination reflects both a commitment to continuity in governance and a promise of retaliation. He decried U.S. and Israeli actions, vowing "the Americans have stabbed the Iranian people in the heart and we will stab them in their heart," emphasizing a strong military response against perceived threats, which he articulated during a state television broadcast, as reported by Al Jazeera and Reuters.

Appointed Secretary of the Supreme National Security Council, Larijani has vast experience in managing Iran's security dynamics and has been involved significantly in nuclear negotiations. He has previously held pivotal roles, including being the speaker of the Parliament for 12 years. His capability in diplomatic relations and crisis management has positioned him as a critical figure during this leadership transition, according to India Times and Al Jazeera.

Iran's constitution mandates that a transitional council oversee governance until a new supreme leader is elected by the Assembly of Experts. Larijani has detailed the roles within this council, underscoring the urgency of establishing order and continuing governance during this critical juncture for Iran, echoing necessary provisions rooted in the constitution, as noted by Al Jazeera and Reuters.
