Former two-term President Mahmud Ahmadinejad, a fierce conservative who was in power during a harsh crackdown on dissenters before seemingly falling afoul of Iran's supreme leader, has registered to run in next month's presidential vote. Although the move by the former hardline president was seen as an attempt to bolster the candidacy of an ally, it was also a challenge to the authority of Iran’s Supreme Leader Ayatollah Ali Khamenei, who had ordered him not to run. President Hassan Rouhani, a moderate who engineered Iran’s 2015 nuclear deal with world powers that secured a removal of international financial and trade sanctions against Tehran, is expected to seek re-election but faces a stiff challenge from conservatives who oppose the deal.
