"The referendum must be annulled and dialogue initiated in the framework of the constitution. We will never hold talks on the results of the referendum," he told Iraqi lawmakers.
"We will impose Iraqi law in the entire region of Kurdistan under the constitution," he said.
The results of Monday's referendum have not yet been announced but an overwhelming "yes" vote was widely expected.
Pressure has been mounting on the Kurds since the vote, not just from Baghdad but also from Ankara, with Turkey threatening a range of measures including cutting off oil exports from the region.
