Iraq election triggers US-Iran power struggle

Preparations for the Iraqi parliamentary elections have been thrown into chaos by a row over whether or not to uphold a ban on hundreds of candidates, because of alleged links to Saddam Hussein's outlawed Baath Party.

The start date for campaigning has been postponed and the Iraqi parliament will hold an emergency session on Sunday to debate the issue.

The dispute reflects both the sectarian fault-lines within Iraq and geopolitical tensions between Washington and Tehran.
