“No official confirmation has been made regarding any potential transfer of power, and media outlets have been unable to confirm it.” “In addition, it is unclear if the succession would be permanent, as it goes against the constitution’s rules regarding appointing a new supreme leader. According to Article 111 of Iran’s constitution, the supreme leader’s successor is to be chosen by the Assembly of Experts, which currently consists of 88 ayatollahs. In the interim, the country would be administered by a provisional leadership council, which would consist of Iran’s president, chief justice and a member of the guardian council. However, according to articles from prestigious think-tank the Washington Institute for Near East Policy, it may not be as simple as that, with outside pressures such as the Islamic Revolutionary Guards Corps (IRGC) likely a role in the process, due to the military body’s influence on the Assembly of Experts.” And you have the power of the Leader himself—he is not constrained by the IRI Constitution.  See “Iran Supreme Leader Khamenei hands power to son due to health – report,” Aaron Reich, Jerusalem Post, December 6, 2020.
