BAGHDAD, Oct. 11 (Xinhuanet) -- One of Iraq's main Sunni Arab political party, the Iraqi Islamic Party, decided on Tuesday to call on its supporters to say "Yes" in this weekend's referendum, a senior member in the party told Xinhua.

    "We have reached an agreement, so now the Islamic Party calls on its supporters to vote yes in the referendum," said Dr. Alaa Meki,  member of the central committee of the party. 

    "The most important thing is that we agree that a committee will be formed four months after the December parliamentary elections and it will have the right to review and make amendments to the constitution," he added.  

    When asked about two heated-discussed points in the draft constitution, federalism and the Arab identity, Meki said "we have solved the problems."

    According to him, the original statement of the "Arab people in Iraq are part of the Arab nation" will be changed into "Iraqi people are part of the Arab nation".

    But he did not specify what kind of changes have been made to the stipulation that Iraq will be a federal state.

    "This is a positive step. This will lead to the successful political process in this country," Meki stressed.

    The Iraqi Islamic Party's endorsement of the constitution came shortly after Iraqi leaders agreed to review possible changes tothe constitution after the legislative elections, a move widely seen as an attempt to get Sunni Arabs' support in the weekend referendum of the charter.

    A spokesman for Iraqi President Jalal Talabani revealed earlier that Shiite, Kurdish and Sunni leaders had reached a basic agreement to amend the constitution, though negotiations are still going on among the leaders to decide on which articles of the constitution would be reviewed, adding an announcement about the details of the change will be released on Wednesday.

    A senior member of Prime Minister Ibrahim Jaafari's Dawa Party also confirmed the accord.

    Sources concerned said the US diplomats had played an importantrole in bringing Iraqi leaders to reach the agreement. 

    However, media reports noted that some Sunni leaders have called upon the community, making up a fifth of Iraq's population, to vote "No" to the charter or boycott the ballot, saying the constitution will marginalize the Sunnis and plunge the country into sectarian strife.  Enditem
