The death in a helicopter crash of president Ebrahim Raisi, seen as a possible successor to supreme leader Ayatollah Ali Khamenei, has reshuffled the cards in the succession process and increased the spotlight on the Iranian number one's son Mojtaba as a contender.
While analysts emphasise it is impossible to know for sure the intentions of Iran's leadership, Raisi's record as a pillar of the Islamic republic over several decades made him an inevitable candidate to become its third supreme leader after Khamenei and revolutionary leader Ayatollah Ruhollah Khomeini.
