A senior adviser to Mahmoud Ahmadinejad, the Iranian president, has resigned.
Ali Akbar Javanfekr, a press adviser to Ahmadinejad, told the student news agency ISNA on Sunday: "I am resigning from the position of media adviser to the president to let him choose a capable and effective person to this position.
"The president is examining necessary changes in the cabinet ... ethically I see it my duty to step down to give him a free hand to appoint an efficient person to this post," Javanfekr said.
"I have not nominated myself for any new posts," he added.
Alireza Ronaghi, Al Jazeera's correspondent in Tehran, said: "He is probably going to be appointed to another position in government ... because, according to law, no Iran government officials have the right to be in more than one position.
"He is a very close and trusted ally of Ahmadinejad and may be appointed to a sensitive position after Ahmadinejad is sworn in."
The Fars news agency said Javanfekr had offered his resignation two weeks ago, but it was not accepted by Ahmadinejad, who is due to be sworn in as president again before parliament on Wednesday.
Ahmadinejad has also faced criticism for sacking Gholam Hossein Mohseni Ejeie, the Iranian intelligence minister, in the final days of the old government amid protests against his re-election, which the opposition charged was fraudulent.
