Bo Guagua, the son of disgraced Chinese politician Bo Xilai, says he hopes his father will be allowed to defend himself “without constraints” at his upcoming trial.
In a statement to the New York Times, Bo Guagua said he had been denied contact with his parents for 18 months.
Bo Xilai – a former party high-flier – goes on trial on Thursday charged with bribery, corruption and abuse of power.
He was expelled from the Communist Party amid a scandal over the murder of a British businessman, Neil Heywood.
Bo Xilai’s wife, Gu Kailai, was jailed in August 2012 for the killing of Neil Heywood, reportedly over a deal gone wrong.
The scandal led to a shake-up at the very top of China’s political elite in the months preceding a once-in-a-decade leadership handover.
Bo Guagua, who was studying in the US when the scandal unfolded, has since kept a low profile.
“It has been 18 months since I have been denied contact with either my father or my mother. I can only surmise the conditions of their clandestine detention and the adversity they each endure in solitude,” he said in a statement to the New York Times.
“I hope that in my father’s upcoming trial, he is granted the opportunity to answer his critics and defend himself without constraints of any kind.”
“However, if my well-being has been bartered for my father’s acquiescence or my mother’s further co-operation, then the verdict will clearly carry no moral weight.”
Some reports have suggested that Gu Kailai may testify against her husband at the trial.
There has been speculation that both the parents agreed to demands from Chinese officials in return for a guarantee that their son would not be pursued.
Bo Guagua also spoke out in defense of his mother, describing her as “silenced and defenseless” and voicing concern about her state of health.
“She has already overcome unimaginable tribulation after the sudden collapse of her physical health in 2006 and subsequent seclusion,” he said.
State media, in reports of Gu Kailai’s trial, said she attributed her actions to a breakdown.
Bo Guagua last released a statement in September, saying he found the allegations against his father hard to believe.
He is soon to begin studying law in New York, he confirmed to the New York Times.
The scandal emerged after Bo Xilai’s police chief, Wang Lijun, fled to the US consulate in February 2012.
A month later, Bo Xilai was removed from his post as party chief in Chongqing and then stripped of his Communist Party posts as his wife was investigated for the murder of Neil Heywood.
Gu Kailai was subsequently convicted of poisoning the businessman to death and is in prison, as is the police chief, Wang Lijun, for abuse of power related to the subsequent cover-up.
Bo Xilai, meanwhile, has not been seen in public since March 2012.
He goes on trial on Thursday in the city of Jinan accused of taking advantage of his office to accept money and property, as well as embezzling public money.
Most political analysts believe that the outcome of the trial has already been decided and that Bo Xilai will almost certainly be found guilty.
