Salem Chalabi, 41, claimed a warrant issued for his arrest in connection with the death of the director general of the Iraqi finance ministry, Haithem Fadhil, is part of an attempt to “humiliate” him and undermine the legal process.
The lawyer and executive director of the Iraqi special tribunal is currently at his London home and has been warned he will be put into custody if he returns to Baghdad.
Mr Chalabi told PA News: “We are working out my return because the results of this could be destabilising to the tribunal process.
“We would hope that they lift this silly warrant and we can get things running again before the judgement of the judiciary is called into question.
“I am more concerned about the way the details of this warrant have been leaked than the allegations themselves, which are ridiculous.”
Iraq’s chief investigating judge Zuhair al-Maliki issued a warrant last week and claims Mr Chalabi made a threat to kill finance official Haithem Fadhil.
It is alleged that Mr Fadhil had prepared a report accusing the Chalabi family of seizing government property.
Mr Chalabi has denied the claims and said he suspects the investigation is part of a plot by Baa’th party loyalists to undermine Saddam’s trial.
He also claimed that the judge who issued the warrant had previously criticised the tribunal process.
“I have had previous death threats and my home in Baghdad’s green zone was shelled with three mortars. People deliberately want to kill me,” Mr Chalabi said.
“I want to return to Baghdad but I have been threatened that they would throw me in jail.
“Through indirect sources I know that they want to humiliate me and threaten my life.”
Mr Chalabi said minutes of the Iraqi Governing Council showed he had been present there on the day he is alleged to have visited Mr Fadhil’s office and threatened him.
He also confirmed that both Prime Minister Iyad Allawi and President Ghazi al-Yawer are directly involved in attempts to secure his return to Baghdad.
It is claimed that if tried and convicted, Mr Chalabi, who has British residency, could face the death penalty, which was restored by Iraqi officials on Sunday.
