BAGHDAD, Aug 23: The Iraqi government on Tuesday ruled out any major change to a draft constitution that parliament looks set to pass this week in the teeth of Sunni objections that it could ignite civil war.

“The draft that was submitted is approximately the draft that will be implemented,” government spokesman Laith Kubba said after parliament received the text before a Monday midnight deadline.

The assembly put off a vote till Thursday to let tempers cool.

Sunni leaders, who largely shunned a January election that gave Shias and Kurds control of parliament, quickly indicated they would try to mobilize support for a ‘no’ vote in the October referendum on the charter.

The constitution will be rejected if two-thirds of voters in three or more of Iraq’s 18 provinces vote ‘no’. The Sunnis are a clear majority in at least three provinces in the heartland of the resistance: Anbar, Salaheddin and Nineveh.

A Sunni delegation met Iraq’s election commission to discuss ways of ensuring participation in those three regions, the commission said in a statement.

President Jalal Talabani, who has brought Iraqi leaders together for weeks in a bid to keep the political process on track and defuse the resistance, renewed mediation efforts.

A statement from his office said the Kurdish leader urged all Iraqi sects to unite on the issue of the constitution.

But all sides held fast to their positions.

The Shia head of the parliamentary drafting committee again made clear he did not intend to reopen contentious clauses such as those on autonomous ‘federal’ regions which Sunnis say discriminate against them and could break up the state.

Humam Hamoudi said the Sunni negotiators brought in from outside parliament were not representative and the assembly should now submit the draft to a referendum.

US diplomats, under pressure from Washington to keep Iraqi negotiators to a timetable laid down under American supervision last year, say they will go on working for a consensus that can draw the Sunnis away from violent opposition.

But one participant in the talks said a comprehensive deal would require a Sunni change of heart. “The only possible change now is that the Sunnis become convinced on federalism,” said Jalal al Din al Sagheer, a Shia delegate on the drafting team.

Shia and Kurd negotiators said they might offer minor concessions, but were ready to use their parliamentary muscle to push through the draft.

SPECTRE OF CIVIL WAR: “If it passes, there will be an uprising in the streets,” Sunni negotiator Saleh al Mutlak said after the brief sitting.
