TARIQ AZIZ: After Saddam himself, the best-known Iraqi leader in the West. The cigar-puffing, bespectacled figure of Tariq Aziz was Iraq's foreign minister at the time of the first Gulf War. He was used by Saddam as a moderate front, regularly appearing on western television screens speaking excellent English. By the time of the 2003 invasion, he had risen to the heights of deputy prime minister, despite being the only Christian in the Sunni-dominated Baathist regime. His cigar case may have turned up in the possession of Boris Johnson recently, but Aziz himself hasn't seen the light of day since he was captured by US troops in April 2003, save for a brief appearance as a defence witness at Saddam's trial. He has been languishing in prison ever since and has yet to face a trial of his own. His health has deteriorated, while an Iraqi Christian leader has demanded his release.
