Saddam Hussein's chief lawyer said Sunday he plans to publish a book in the coming year disclosing secret information about the executed Iraqi leader.

"Any lawyer who worked on such a big case has the right to write his [Saddam's] diary," said Khalil al-Dulaimi, a Baghdad attorney, who served as Saddam's confidante and main legal counsel since the deposed dictator's interrogation by U.S. and Iraqi authorities on June 14, 2005.

Al-Dulaimi said his book would "clear up some points about facts that haven't yet been announced." He would not say whether he had already started writing the book but said he would reprint as many as 300 personal letters, poems and other miscellaneous works written by the deposed leader.

"I will write everything about the court, the Americans, and the way they used to treat him," al-Dulaimi said in a telephone interview.

"I'm also going to talk about how Baghdad fell at the hands of Americans and the way they entered and captured Baghdad," he added.

Saddam was sentenced to death last November for the killing of 148 Shiites in Dujail after a 1982 attempt to assassinate him. He was executed on Dec. 30, 2006 in an unruly scene that brought worldwide criticism of the Iraqi government. Video of the execution, recorded on a cell phone camera, showed the former dictator being taunted as he stood with a noose around his neck on the gallows.
