After Khamenei: Who Will Succeed Iran's Supreme Leader?

Since succeeding the Supreme Leader Ayatollah Khomeini in 1989, Ali Khamenei has striven to make himself indispensible to the fate of Islamic fundamentalism in Iran. However, the measures Khamenei has taken to secure his power have left his succession in doubt, with no consensus heir. The lack of clear successors among the clergy, weakness of the government institutions, and concerns about regime strength could lead to instability and the potential for an Islamic Revolution Guard Corps coup.
