Iran power struggle

On Monday, Iran's supreme leader Ayatollah Ali Khamenei endorsed Mahmoud Ahmadinejad as president for a second term. Ahmadinejad has just been sworn in, but the way ahead is still tough.

In politics, body language tells a lot.

Amir Paivar, Iranian analyst, said, "That moment of pause, of confusion, of hesitation will probably symbolize what their relationship will be in the next four years--a kind of troubled, confused relationship between the two."

Ahmadinejad won over 60 percent of the votes in June's presidential election. The election generated a record 85 percent turnout.

But it sent Iran into its worst internal divisions since the 1979 Islamic Revolution. Opponents claimed the vote was rigged. At least 30 people died in the unrest. More than 100 people, including reformist political figures, face trial for supporting the post-election unrest.

Ayatollah Ali Khamenei, Iran's Supreme Leader, said, "The enemy should not be mistaken in its understanding of the Islamic Revolution and the Islamic ruling system. They must not wrongly suppose that they can bring the Islamic revolution and system to its knees with their useless measures."
