"I think it will be in the middle or the end of August," the source, who asked to remain anonymous, told AFP, when asked when the trial would take place. He is likely to face charges of bribery and abuse of power.
Bo, the former party boss of southwestern megacity Chongqing, was ousted from the ruling Communist party last year, after the government accused him of accepting "massive" bribes, and bending the law, following his wife's conviction for the murder of a British businessman.
News of the trial comes at a time when the Communist Party is attempting to show it is cracking down on corruption and government waste.
Bo's trial will take place in Jinan, the capital of eastern China's Shandong province, the South China Morning Post Newspaper reported today, citing official sources in Chongqing.

Officials in the city met "to detail formal charges" against Bo ahead of the trial, the newspaper reported.
China's official media earlier reported that Bo's case had been passed over to legal authorities, following an internal party investigation which resulted in his expulsion.
Bo, the son of one of China's most famous revolutionary leaders, is still thought to have high-level allies within the party -- and his trial is likely to be short and tightly staged-managed, with the result decided in advance as a result of behind the scenes political bargaining.
