Former president Akbar Hashemi Rafsanjani threw himself into Iran's election race on Saturday as a flurry of heavyweight candidates rushed to beat the registration deadline in the most unpredictable contest for decades.Rafsanjani, 78, who was president from 1989 to 1997, is expected to draw some support from reformists because he backed the opposition movement whose protests were crushed after the last, disputed election in 2009.
The election comes at a critical moment, as Iran reels from international sanctions over its disputed nuclear program and faces the threat of attack by Israel if it attempts to acquire a nuclear weapon - an intention it strenuously denies. A vast field of more than 400 candidates have thrown their names into the ring as potential successors to outgoing president Mahmoud Ahmadinejad.
Shortly before Rafsanjani's announcement, Saeed Jalili, a hardline conservative who is seen as close to Khamenei and has led rounds of so far unsuccessful nuclear talks with world powers, entered his name as a candidate. Soon afterwards, ISNA news agency reported the registration of Esfandiar Rahim Mashaie, an aide to Ahmadinejad and a man viewed with intense distrust by conservatives. Khamenei's camp sees Mashaie as leading a "deviant current" that seeks to set aside clerical influence in favor of a more nationalistic doctrine.
With Iran's economy reeling from international sanctions over the nuclear dispute, the outcome of the contest on June 14 will signal the extent of Khamenei's control at the summit of power in the Islamic Republic.
