BAGHDAD, May 8 (IslamOnline.net & News Agencies) - The core group of Iraqi politicians supported by the United States to oversee the birth of a new government in post-Saddam Iraq agreed to admit two extra members to the five-man leadership committee.

"We have decided to enlarge the leadership committee by adding two seats -- one for a representative of al-Da’wa Party and one for Naseer Kamel Chaderchi as a representative of the Sunni Arabs," Patriotic Union of Kurdistan (PUK) leader Jalal Talabani told reporters.

He added four additional political parties had agreed to join the organizing committee for a national conference, due to begin by the end of May, that will form a government and fill the political vacuum in the war-scarred country.

They are al-Da’wa Party, the Iraqi Islamic Party, the Communist Party of Iraq and the Arab Socialist Movement, reported Agence France-Presse (AFP).

Former Iraqi foreign minister Adnan Pachachi, tipped for a key role in post-Saddam Iraq, had also "agreed to attend the national conference and to prepare for it," Talabani said without specifying whether he would take up a seat on the organizing committee.

Returning to Iraq after 33 years in exile, Pachachi, who has declined a seat on the U.S.-sanctioned leadership council, insisted he would only take part in an interim government if he were elected.

The core group, which also includes Massoud Barzani of the Kurdistan Democratic Party (KDP), Abdul Aziz al-Hakim, number two of the Iran-based Shiite Supreme Assembly of the Islamic Revolution in Iraq (SAIRI), U.S.-backed Ahmad Chalabi of the Iraqi National Congress, and Iyad Allawi of the Iraqi National Accord, then met with U.S. civil administrator Jay Garner.

Emerging from the talks, Garner told reporters after the talks: "We continue to discuss the process of raising a democracy."

Chalabi said they had reached a deal with the Americans "to cooperate on security and information about the Baath party membership in order to eradicate the remains of the Saddam leadership which is still in Iraq."

Security has become the main issue in the largely lawless country.

"I think what you may see is as many as seven, eight, nine leaders working together to provide leadership," he said.

Garner asserted the group would likely be expanded to include a Christian and perhaps another Sunni figure, adding he did not know how the collective leadership would function specifically.

The creation of the new government should see appointments to the 23 main ministries which were in place under Saddam, with the top spots likely going to the council members now leading the negotiations.

It remains unclear how long an interim government would run the country before an election is held, or when the Anglo-American forces would be ready to hand over full power.

Dozens of political groups have sprung up since Saddam's fall but most have small followings.
