Politicians in Iraq have called for the permanent exile of the Iraqi defector, codenamed Curveball by his US and German handlers, who admitted to the Guardian he lied about Iraq having weapons of mass destruction (WMD).
Rafid Ahmed Alwan al-Janabi said he invented stories about Saddam Hussein's non-existent bioweapons programme in order to "liberate" Iraq.
But if he thought that his mea culpa would make him a hero, it seems he was wrong. "He is a liar, he will not serve his country," one Iraqi politician said in response to Curveball's claim to want to build a political career in his motherland.
In his adopted home of Germany, politicians are demanding to know why the German secret service, the Bundesnachrichtendienst (BND), paid Curveball €3,000 (£2,500) a month for at least five years after they knew he had lied.
In the US, questions are being asked of the CIA's handling of Curveball, 43, and specifically why the then head of the intelligence agency, George Tenet, did not pass on warnings from the Germans about Curveball's reliability.
But the harshest criticism of Curveball is coming from Iraq.
Jamal Al Battikh, the country's minister for tribes' affairs, said: "Honestly, this man led Iraq to a catastrophe and a disaster. Iraqis paid a heavy price for his lies – the invasion of 2003 destroyed Iraqi basic infrastructure and after eight years we cannot fix electricity. Plus thousands of Iraqis have died.
"This man is not welcome back. In fact, Iraqis should complain against him and sue him for his lies."
Others poured scorn on Curveball's plan to return to Iraq and enter politics.
Intefadh Qanber, spokesman for the Iraqi National Congress (INC), led by Ahmed Chalabi, said: "He is a liar, he will not serve his country. He fabricated the story about WMD and that story gave the USA a suitable pretext to lead the 2003 invasion, which hurt Iraq. For most Iraqis, it was obvious that Saddam was a dictator, but they wanted to see him ousted on the basis of his crimes against human rights, not a fabricated story about weapons of mass destruction."
In the US, a pressure group representing veterans of the Iraq war demanded the justice department open an investigation into the INC's relationship to Curveball.
