BAGHDAD, Iraq (CNN) -- The Iraqi Presidency Council approved a resolution Sunday that will allow non-U.S. foreign troops to remain in Iraq after a U.N. mandate expires at year's end. British troops talk in Basra last week. Iraq on Sunday OK'd foreign troops to remain in the country after the new year. It was the last step for final adoption of the resolution, which won parliamentary approval Tuesday. Iraq's main political parties hammered out the resolution a week ago, after an impasse among parliamentary factions threatened to continue beyond the December 31 deadline. A separate, previously approved agreement authorizes U.S. troops to remain.
