One of Iraq's two vice-presidents has vetoed part of the country's new election law, putting the Parliamentary polls scheduled for January in doubt. Tariq al-Hashemi, a Sunni Arab, revoked Article 1 of the law and called for the representation in Parliament of displaced people to increase to 15 per cent.<br/> Most Iraqis who have fled violence since 2003 are thought to be Sunni. The law, which MPs approved after much delay 10 days ago, will now go back to Parliament for further discussion. Mr Hashemi said he believed the issue could be dealt with in one Parliamentary session and need not delay the elections, although the Iraqi Independent Electoral Commission and the UN have warned time is running out.<br/> No final date has been set for the election, but it is expected to be held third week of January. Constitutionally, it must be held before the end of that month.
