A born-again Christian, [Duch] is said to have co-operated with investigating judges - and is expected to reveal important information about the decisions made by the organisation's leadership.

His information could help in the trials set for later this year of four other defendants, analysts say.

They include the surviving top leaders Nuon Chea, Ieng Sary and Khieu Samphan, who are all elderly and in poor health. All four have denied any knowledge of the atrocities that took place under their rule.

If preparations for their trials get bogged down, as seems likely, Duch may be the only man ever held to account for the Khmer Rouge atrocities, our correspondent adds.
