Ahmadinejad threatens to expose spy case details to embarrass opponents

Iranian President Mahmoud Ahmadinejad threatened Wednesday his government would expose details of conversations between a former Iranian nuclear negotiator whom the president had labeled a spy, and foreigners he was accused of colluding with. But an increasing number of conservatives stepped forward to defend negotiator Hossein Mousavian, in a sign the issue was further eroding hardline Ahmadinejad's support. The president's threat was in response to Mousavian's acquittal Tuesday in a case that has become a centerpiece in the feud between hard-line Ahmadinejad and his more liberal political rivals.
