A Chinese court sentenced the wife of disgraced Politburo member Bo Xilai to death on Monday but suspended her execution, ending one chapter in a scandal that has shaken the ruling Communist Party ahead of a leadership transition later this year.

The sentence means Gu Kailai is likely to face life in jail for murdering British businessman Neil Heywood last year, provided she does not commit offences in the next two years.

'The verdict is just and reflects a special respect toward the law, reality and life,' Gu said of the sentence, according to a spokesman for the court, Tang Yigan. She wore a white shirt and dark suit for the hearing, said a witness to the proceeding.

'The court determined that Bogu Kailai is guilty of murder and sentenced her to death with a two year reprieve, with her political rights revoked for the remainder of her life,' Tang told reporters after the hearing in the eastern city of Hefei, referring to Gu by her formal name.

At a trial on August 9, Gu admitted to poisoning Heywood in November, and alleged that a business dispute between them led him to threaten her son, Bo Guagua, according to official accounts published by state media.

The spokesman Tang said the court had concluded that Heywood made threatening words against Bo Guagua, but had never acted on those words. The court also found that Gu's actions reflected a 'psychological impairment', which he did not specify.

The court also said Zhang Xiaojun, an aide to the Bo household, was sentenced to nine years in prison for acting as an accomplice to the poisoning of Heywood.

'With both of the defendants declining to appeal, this marks the end of things,' Zhang's lawyer, Li Renting, told Reuters.

In a separate trial, four Chinese policemen were also convicted on Monday of having sought to protect Gu from investigation, receiving jail sentences of between five and 11 years -- a development that could prove damaging for Bo.

The court that tried Gu and Zhang noted that Heywood had written an e-mail in which he made threats against Bo Guagua but found no evidence 'confirming that he took harmful actions' against the young man.

'Therefore the argument of the defendants of Bogu Kailai and Zhang Xiaojun does not stand and the court rejected the argument,' the court official, Tang, said.

Gu and Zhang should be allowed to see their families 10 days after the verdicts, provided neither lodges an appeal, said Li Xiaolin, another family lawyer for the accomplice, Zhang.

Gu's sentencing could be a prelude to formal punishment of Bo Xilai, a brashly ambitious politician under investigation for alleged violations of party discipline -- an accusation that covers corruption, abuse of power and other misdeeds. After the party leadership decides on those allegations, Bo Xilai could also face criminal charges related to the murder case.

Bo's hopes for securing a spot in China's next top leadership unraveled after his former police chief, Wang Lijun, fled to a U.S. consulate in early February for about 24 hours and exposed the murder allegations.

Britain's embassy in China said in an e-mailed statement that it welcomed the 'fact that the Chinese authorities have investigated the death of Neil Heywood and tried those they identified as responsible'.

It added that Britain had 'consistently made clear to the Chinese authorities that we wanted to see the trials in this case conform to international human rights standards and for the death penalty not to be applied'.

Bo, the son of a revolutionary, ran the southwestern city of Chongqing where Heywood was killed. Bo was seen as competing for a place in the Politburo Standing Committee, the body at the pinnacle of power in China, at a once-in-a-decade leadership transition later this year.

His downfall has stirred more division than that of any other leader for over two decades. To leftist supporters, Bo was a charismatic rallying figure for efforts to reimpose party control over dizzying, unequal market-led growth.

But he made powerful enemies among those who saw him as an opportunist who wanted to impose his policies on the country.

Bo was sacked as Chongqing boss in March and Gu was publicly accused of the murder in April, when Bo was suspended from the Politburo, a 25-member elite council that ranks below the Standing Committee. He has yet to be expelled from that council.

Police sources in Chongqing have said Bo tried to shut down the investigation into his wife after being told she was a suspect.
