The Spanish Foreign Minister, Ana Palacio, has said that Spain, the US and Britain may not present a second UN resolution because France is sure to veto it.
Ms Palacio was speaking in Madrid, after an earlier meeting in Paris with her French counterpart Dominique de Villepin.
Previously, the US had said it would force a vote so that the five permanent and 10 temporary members of the UN Security Council would have to take a stand publicly.
Spain has been one of the United States' most active supporters on Iraq.
Tony Blair warns of 'message of weakness'
Tony Blair today warned that leaving British and US troops in the Gulf with an indefinite timetable and without clearly insisting on disarmament would send a message of weakness not just to Saddam Hussein but across the world.
Mr Blair called on Security Council members to reconsider threats to use their veto.
He warned that using the veto would put at risk not just the disarmament of Iraq but the unity of the UN.
Mr Blair told MPs in the Commons today that Saddam Hussein could avoid war now by complying with Resolution 1441.
He added that the worst thing that could happen is for him to defy the will of the UN and then for no action to take place.
Six conditions
This morning, the Foreign Office said the Iraqi leader must comply with six conditions to avoid war.
Foreign Office minister Mike O'Brien said the conditions, which London wants to attach to a draft second resolution on Iraq, were being discussed with fellow UN Security Council members.
The conditions are:
* Make a public statement, to be broadcast in Iraq and outside, admitting he has weapons of mass destruction and will give them up;
* Allow 30 Iraqi scientists to be interviewed outside Iraq with their families in tow;
* Surrender stocks of anthrax and other biological and chemical agents which U.N. weapons inspectors said Iraq had in 1998, or produce documents to demonstrate what happened to them;
* Pledge to destroy banned missiles;
* Account for unmanned aerial vehicles, known as "drones", which can spray chemical agents over wide areas;
* Give a commitment to give up all mobile bio-production laboratories for destruction.
EU warns on funding
The European Commission this morning warned that the EU might be unwilling to help fund the reconstruction of Iraq if the US went to war without UN authority.
The EU's External Relations Commissioner, Chris Patten, told the European Parliament that launching military action without proper UN backing would do enormous damage to the world body, to NATO and to transatlantic relations.
Mr Patten also said a war in Iraq would be likely to encourage terrorism, especially if the US failed to work harder for peace between Israel and the Palestinians.
Taoiseach to outline Govt's position on Iraq
The Taoiseach has told the Dáil that he will spell out the Government's position on Iraq during his visit to the US in the next few days.
Bertie Ahern said Ireland wanted a second UN resolution as it would create difficulties for everybody otherwise.
Mr Ahern was also asked about the use of Shannon airport by US military forces.
He said that precedents such as Vietnam and Kosovo suggested the airport could be used even in the event of unilateral action by the US against Iraq.
