Following the reported death of Iran's Supreme Leader Ali Khamenei due to an attack allegedly orchestrated by the US and Israel, the political landscape of the Islamic Republic is under scrutiny. Notably, both Donald Trump and Israeli Prime Minister Netanyahu have claimed responsibility, while Iranian state media has confirmed Khamenei's death. This development leads to significant concern over the power vacuum in Iran and who might emerge as the next Supreme Leader, as Khamenei had not publicly designated a successor during his lifetime.

According to the Iranian Constitution's 'Velayat-e-Faqih' system, the position of Supreme Leader is reserved for a high-ranking religious scholar. Presently, the only prominent candidates are Khamenei’s son, Mojtaba Khamenei, and the grandson of Iran's founder, Ayatollah Khomeini, Hassan Khomeini. Both candidates represent starkly different potential directions for the Islamic Republic. Mojtaba is viewed as a continuation of Khamenei's policies, while Hassan could signify a possible shift depending on his interpretations and intentions.

The succession of Khamenei presents a formidable challenge. Current reports suggest no individual currently possesses the same authority Khamenei held, complicating the selection of a successor. The new leader will face immense pressure from powerful institutions such as the Revolutionary Guards and significant religious bodies. The outcome of this power struggle will have profound implications on Iran’s domestic policies and international relations, particularly regarding ongoing tensions with the US and Israel.
