Official Iranian news reports say parliament has rejected President Mahmoud Ahmadinejad's third nominee for the post of oil minister.
The reports say Mohsen Tasalouti - a trained architect - failed Wednesday to win a vote of confidence, after lawmakers argued he was not qualified to run the all-important ministry. Oil exports generate 80 percent of Iran's public revenues.
The president's first nominee for the post, Ali Saeedlou was rejected in August by lawmakers who said he was not qualified.
A second nominee, General Sadeq Mahsouli - a Revolutionary Guards commander with no oil experience - withdrew his candidacy earlier this month when it became clear parliament would reject him as well.
The ministry is currently being run by a deputy oil minister under former President Mohammed Khatami.
