JINAN - Ousted senior Chinese politician Bo Xilai angrily ripped into his former police chief on Sunday on the fourth day of his trial, calling him a "vile character" who faked testimony accusing Bo of covering up a murder committed by his wife.
Bo was a rising star in China's leadership circles when his career was stopped short last year by a murder scandal which saw his wife Gu Kailai convicted of poisoning a British businessman.
Bo is now on trial charged with corruption, taking bribes and abuse of power, the last of which is especially sensitive as it involves allegations Bo challenged the authority of the ruling Communist Party.
Despite Bo's feisty defence, a guilty verdict is a foregone conclusion as China's courts are controlled by the Communist Party. State media, which speaks for the party, has already all but condemned him.
Since the trial began on Thursday in eastern Jinan city, Bo has repeatedly said he is not guilty of any wrongdoing and has called his wife's testimony against him the ravings of a mad woman.
On Sunday, Bo rebutted earlier testimony from his former police chief Wang Lijun, who carried out Bo's crackdown on crime and gangs in Chongqing, where Bo was Communist Party chief.
Wang said he had told Bo that his wife Gu, once a glamorous lawyer, had murdered British businessman Neil Heywood.
