Iraq's parliament confirmed it will meet on Wednesday to amend the draft constitution after a deal proposing last-minute changes won support from at least one influential Sunni Arab group. But opposition remained strong among other Sunni parties. With three days left to a referendum, a parliament spokesman said parliament would begin its meeting at 7 p.m. (1600 GMT). "There were meetings over the last few days. They reached results and we are waiting to put them to the National Assembly today for endorsement to assure the success of the constitution," said Muhand Abdul Jabar, media director for the speaker's office. Reuters quoted Officials in the ruling Shi'ite majority as saying four articles of the present draft constitution would be amended. "There will be a vote on these four amendments," said Saad Qandeel, a member of parliament's constitutional drafting committee, adding that they would need a two-thirds majority vote -- a fairly easy hurdle for the ruling coalition.
