The prosecution countered by saying Bo should be severely punished because he showed no remorse during the five-day corruption trial that offered lurid glimpses into the life of an elite Chinese family and its subsequent undoing.
Bo's hints at a love triangle involving his wife, Gu Kailai, and his former police chief, Wang Lijun - both of whom testified against the former politburo member - came after he had denounced the pair during proceedings.
Bo told the court: "He (Mr Lijun) was secretly in love with Gu Kailai, his emotions were tangled and he could not extricate himself," .
The corruption trial comes in the wake of the scandal set off by Bo's wife's murder of British businessman Neil Heywood in late 2011.
Prosecutors said the proceedings have shown adequate proof of Bo's guilt of taking bribes, embezzlement and abuse of power in interfering with the murder investigation.
The verdict is expected at a date to be announced.
