Bo Xilai Scandal: Gu Kailai Trial for Heywood Murder Ends
Ms Gu had not contested the charge that she killed Mr Heywood by poisoning in 2011.
The date of the verdict would be announced later, the official said.
Ms Gu is the wife of former high-flying politician Bo Xilai, whose career in office was ended by the scandal surrounding Mr Heywood’s death.
Ms Gu, herself a prominent lawyer, is on trial along with her aide, Zhang Xiaojun, who was described by the court as an accomplice.
In an unusual news briefing outside the court, the court official, Tang Yigan, said Ms Gu and Mr Zhang “did not raise objections to the facts and the charges of intentional homicide”.
