The dispute appears to stem from an ongoing confrontation between Ahmadinejad and the ruling clerics in Iran following years of tensions over power struggles. It could also herald potential difficulties for Ahmadinejad's protege, Esfandiar Rahim Mashaei, to be cleared for the June 14 presidential election, which is to pick Ahmadinejad's successor. The president himself is not running since Iran's constitution bars him from seeking a third term in office. The group that complained on Sunday, the Guardian Council, also vets all candidates for the presidency. Mashaei is among more than 680 hopefuls, but no more than a handful will be selected for the final ballot. State TV quoted Guardian Council spokesman Abbas Ali Kadkhodaei as saying the claims against Ahmadinejad will be referred to the country's judiciary for possible charges. The Council's members said that public fund rules were broken when Ahmadinejad accompanied Mashaei to the election registration office on Saturday, said Kadkhodaei. A conviction could bring a maximum punishment of six months in jail or 74 lashes. Kadkhodaei did not elaborate. Ahmadinejad has strongly pushed Mashaei as his political heir, but there are serious obstacles to his protege making the final ballot. As part of Ahmadinejad's disputes with the ruling clerics, Mashaei has been denounced by hard-liners as leader of a "deviant current" that seeks to undermine Islamic rule. Mashaei has long been Ahmadinejad's close confidant, and the president's son is married to Mashaei's daughter. State TV on Saturday showed a smiling Ahmadinejad accompanying Mashaei as he submitted his papers at the registry office, and the president raised his aide's hand in a gesture of support. — AP
