Indonesian prosecutors have asked a court to sentence one of the accused Bali bombers to life in prison.
The ABC reports Umar Patek has admitted to mixing the chemicals, but says he played no part in assembling the bombs that killed 202 people, on 12 October, 2002. The dead included 88 Australians and two New Zealanders.
Patek was arrested in January last year in the town of Abbottabad, Pakistan, four months before Al Qaeda chief Osama bin Laden was killed there.
But the prosecutor told the West Jakarta District Court on Monday that because Patek has shown contrition, he should be spared the death penalty.
''We the prosecutors recommend... the defendant Umar Patek be given a life sentence," Bambang Suharyadi told the court.
''He has been polite and cooperative during the trial and regretted what he has done.''
As the trial drew to a close earlier this month he apologised to all of the victims. He repeated that apology on Monday.
"I regret what I have done... (and) I apologise to the families of victims who died - Indonesians and foreigners," he said.
He is also charged with mixing explosives used in attacks on churches in Jakarta on Christmas Eve in 2000, and knowing about a terrorist training camp established in Aceh in 2009 but failing to report it to police.
He is accused of being the expert bomb maker for Jemaah Islamiyah, a South East Asian terror network linked to Al Qaeda.
Patek is charged with premeditated murder. The verdict is expected on 21 June.
Three JI members - Mukhlas, Amrozi and Imam Samudra - were executed by firing squad in November 2008 for their roles in the attacks.
