A look at some of the contenders to be Iran’s supreme leader after the killing of Khamenei

Following the death of Supreme Leader Ayatollah Ali Khamenei in a U.S. and Israeli bombardment, Iran is facing a succession crisis as it chooses its second supreme leader since the 1979 Islamic Revolution. Potential replacements include hard-liners favoring confrontation with the West and reformists seeking diplomacy. The supreme leader holds ultimate authority over key decisions, including matters of war, peace, and the nuclear program. Currently, a provisional governing council consisting of President Masoud Pezeshkian, judiciary chief Gholamhossein Mohseni Ejei, and cleric Ayatollah Ali Reza Arafi is managing the country during this critical period. The Foreign Minister is Abbas Aragh.

The US and Israel launched attacks on Iran, resulting in the death of Supreme Leader Ayatollah Ali Khamenei, escalating tensions in the Middle East. Iran has vowed retaliation, drawing regional powers into the conflict. Iranian President Masoud Pezeshkian, judiciary chief Gholamhossein Mohseni Ejei, and senior cleric Alireza Arafi will lead Iran in the transitional period. Donald Trump expressed willingness to negotiate with the remaining Iranian leadership. Elsewhere, the UK's RAF Akrotiri base in Cyprus was hit by a suspected drone strike, causing minor damage. In the UK, new asylum rules designate refugee status as temporary, lasting 30 months, and the Green Party's membership surpassed 200,000 after a byelection victory. Concerns are also rising about the potential impact of data centers on the UK's greenhouse gas emissions.

Following the death of Supreme Leader Ayatollah Ali Khamenei in a US-Israeli attack on March 1, 2026, Iran has formed a three-member transitional council to govern the country. The council consists of Ayatollah Alireza Arafi, President Masoud Pezeshkian, and Chief Justice Gholam-Hossein Mohseni-Ejei. Arafi's appointment was confirmed by the Expediency Council. According to the Iranian Constitution, this council will oversee state duties until the Assembly of Experts, an 88-member panel, selects a new supreme leader. The Islamic Revolutionary Guard Corps (IRGC) and security chief Ali Larijani are also expected to play significant roles during the transition. The commander-in-chief of the IRGC was also killed in the same attack.

Upon the death of Iran's Supreme Leader, Ayatollah Ali Khamenei, the 88-member Assembly of Experts, a council of Shiite clerics, is responsible for selecting his replacement. This panel, elected every eight years and vetted by the Guardian Council, has the power to appoint and theoretically remove the Supreme Leader. Iranian law mandates a swift selection process; however, a temporary leadership council can assume duties in the interim. This council would consist of Iran's president, the head of the judiciary, and a member of the Guardian Council. The succession process is complex due to the structure of Iran's theocracy and the vetting process for the Assembly of Experts.
