TEHRAN (Reuters) - Iranian lawmakers looked set to call in President Mahmoud Ahmadinejad for questioning as, once again, enough members of parliament signed a summons, media reported on Monday.

Parliament had dropped the four-month-old motion that may lead to Ahmadinejad's impeachment last week.

"Plan to question Ahmadinejad back on track with increased signatures," ran the front page headline on Siasat-e Rouz daily which, like most papers, led with the story that shows a serious internal political rift is far from healed.
