Economy is crucial in Iran's presidential poll

In the run-up to Iranian presidential election on Friday, supporters of the rival candidates have gathered on the final day of campaigning.

Those who are against the incumbent president Mahmoud Ahmadinejad accuse him of leading the country's economy into a dire situation. And they want change, which they hope the reformist candidate Mirhossein Mousavi might bring about.

The economy seems to be the Achilles heel of incumbent President Mahmoud Ahmadinejad who is struggling to win a second term in the upcoming presidential vote.

Ahmadinejad was elected on a platform that included bringing oil revenues to every family, eradicating poverty, and tackling inflation and unemployment.

His failure to keep those promises has turned even some of his conservative supporters against him.

Mohsen Safaei Farahani, Former Reformist Legislator, said, "We've had an unsuccessful four-year period, because having enough time and human and cash resources, we could have strengthened our economic infrastructure. Now it is all lost because we failed to have good management."
