Tensions in Tehran: Ahmadinejad versus the Ayatollah?

Iran's Supreme Leader Ayatollah Khamenei and President Mahmoud Ahmadinejad appeared united in public on Saturday, despite reports of a rift between them. Ahmadinejad has been under fire recently from the country's conservatives who accuse him of trying to increase his power by getting rid of certain ministers. But the Ayatollah seemed to defend the President at the weekend.
