Iraq's newly elected vice-presidents are expected to represent their religious communities in Iraq's three-man presidency council, headed by veteran Kurdish politician Jalal Talabani.
SUNNI ARAB TRIBAL CHIEF
Ghazi Yawer is a former businessman and tribal leader.
The 46-year-old US-educated moderate Sunni Arab and former exile has strong ties to Washington, although he has been sharply critical of the US-led coalition.
A member of the huge Shammar tribe from the northern city of Mosul who generally appears in traditional Arab dress, Mr Yawer has wide also support from various ethnic and religious groups.
He studied engineering at Georgetown University in Washington, and for many years ran a telecoms company in Saudi Arabia.
He beat his US-backed Sunni Arab rival Adnan Pachachi for the position of VP, in an echo of the way he beat him to the interim presidency in 2004.
This reflects the Shia and Kurdish backing that he has consolidated in his 10 months in office.
However, analysts say his record has been patchy, having largely failed to get his community out to vote in the January elections or to persuade them to turn away from the Sunni-led insurgency.
Adel Abdul Mahdi is a francophone Islamist and free-marketeer who belongs to the Shia-led list that won a majority of seats in the Iraqi parliament.
The 62-year-old served as finance minister in the interim government, where he persuaded international creditors to write off a large part of Iraq's debt.
He fled Iraq in the 1960s after being condemned to death for his political activities, and has spent time in France, Lebanon and Iran.
After flirting with Maoist politics in France, he joined the Supreme Council for the Islamic Revolution in Iraq (Sciri) - a powerful Shia organisation which manages to keep close ties with Iran and maintain a working relationship with the US.
He has a PhD in economics from France and his four children all hold French nationality.
His nomination as one of the two vice-presidents comes after he failed to win enough support to become prime minister - the most important political role.
That honour seems likely to fall to a leader of the other largest Shia party, Ibrahim Jaafari of the Daawa party.
