Iraq's cabinet has approved changes to a draft oil law, and sent it to parliament in an attempt to curb the sectarian violence.
Nuri al-Maliki, Iraq's prime minister, said it was the "most important" law in the country.
"The law was approved unanimously ... it was referred to the parliament which will discuss it tomorrow.
I call on all our partners in the political process and in this national unity government to respect this deal."
However, the Kurds have said that they had neither seen nor approved the final text of the law and might oppose it.
The Kurdistan regional government said it would reject the latest text, if it made "material and substantive changes" to the outline agreed upon during weeks of protracted negotiations.
For the Iraqi people, time is running out.
