May 26, 2004 -- WASHINGTON — The likely head of the new Iraqi government that takes power June 30 is a Shiite nuclear scientist jailed for years in Abu Ghraib prison for refusing to help Saddam Hussein make nuclear weapons, it was reported yesterday. The expected appointee is Hussain Shahristani, 62, a political novice close to the Grand Ayatollah Ali Sistani, Iraq's most powerful cleric, The Washington Post said. "If they consider my participation essential, I'll try to convince them otherwise. But if they're not convinced . . . I cannot refuse," Shahristani told the paper. Post Wire Services
