Iran's disputed President Mahmoud Ahmadinejad will be sworn in for a second four-year term before parliament between July 26 and August 19, the Islamic Republic News Agency (IRNA)reported on its website.

Ahmadinejad was declared winner of the presidential election on June 12. While the defeated presidential candidates, Mir Hossein Mousavi, Mehdi Karroubi and Mohsen Rezaei claimed the election to be fraud.

The parliament's presiding board has already set the timeframe for the swearing-in ceremony and the introduction of the new cabinet, IRNA reported.

And the Parliament will debate the credentials of the incoming ministers during that period, the report said.

The Guardian Council which is supervising the elections has ruled out early this week any possibility of nullifying the vote and insisted that the vote was free and fair with only minor irregularities.
