Iran's Parliament summoned President Mahmoud Ahmadinejad for questioning, semi-official Mehr news agency said on Monday, raising tensions in a power struggle between factions in the ruling elite. Ahmadinejad - facing parliamentary elections next year and a
presidential race in 2013 - must attend the assembly within a month, Mehr said, after 100 lawmakers signed a motion calling him in.(snip)The conservative-dominated Parliament has often used its constitutional powers against Ahmadinejad, particularly over ministerial appointments
and budgetary matters, and most recently rejected a close ally he
nominated as deputy foreign minister.
