The high-profile murder trial of the wife of disgraced Chinese politician Bo Xilai ended after just one day on Thursday.

A court official in the eastern city of Hefei said a verdict has not been delivered in the case. He said the defendant, Gu Kailai, did not object to the charges and is in “good shape and mentally stable.”

Prosecutors say Gu and her butler poisoned British businessman Neil Heywood in November in the southwestern city Chongqing, where Bo was Communist Party leader.

If convicted, Gu faces a possible death penalty. The official Xinhua news agency says four police officials who attempted to “cover up” the murder of Heywood will also go on trial this week.

The case is China's most politically sensitive in recent memory and has already brought down Gu's husband, Bo Xilai, who was once considered a rising star in Chinese politics.

The son of a famous revolutionary leader, the charismatic Bo had been a top contender for the Politburo Standing Committee, China's top decision-making body, before he was stripped of his political posts earlier this year. Although Bo is being investigated for corruption, his fate is still unknown and he has not been heard from in months.

The scandal comes at a sensitive time for China's Communist Party, which is set to undergo a rare leadership transition later this year.
