HEFEI, China — China's most politically sensitive trial in three decades ended in just about seven hours on Thursday after the wife of ousted Politburo member Bo Xilai did not contest charges of murdering a British businessman, a court official said. A verdict will be delivered at a later date. The official's account of the closed-door hearing in the eastern Chinese city of Hefei signals that Gu Kailai and a family aide are sure to be convicted in a case that has ended her husband's career and rocked China's leadership. “The trial finished this afternoon and the court adjourned,” official Tang Yigan told reporters. “The trial committee will announce the verdict after discussion. The date of the verdict will be announced. “The accused (Gu) Kailai and Zhang Xiaojun did not raise objections to the facts and the charges of intentional homicide.” Gu's trial is seen by many Chinese as part of a push against Bo, an ambitious populist who made powerful enemies as he campaigned to join the next generation of top central leaders. Bo was formerly considered a contender for the inner sanctum of power — the party's Politburo Standing Committee — in a once-in-a-decade leadership transition that is currently underway. The new leadership is expected to be unveiled in October. Gu and her co-accused were charged with poisoning Briton Neil Heywood, a family friend, last year. The official said the court was told Zhang, the family aide, had put poison in a drink of water that Gu then gave to Heywood who was drunk at the time. His body was found last November in a hotel in Chongqing, the city where Bo was the Communist Party chief. Gu and Zhang face the death penalty if convicted. But many legal experts expect Gu will be convicted but only sentenced to a lengthy jail term. Entry to the courtroom, in the capital of Anhui province, was restricted but two British diplomats were invited to be present because of the nationality of the victim. Journalists were not allowed in. As the trial took place, police dragged away two Bo supporters into an unmarked car after they had appeared outside the courthouse, singing patriotic songs that were the trademark of Bo's populist leadership style and condemning the trial as a sham. State censorship of Internet chatter on the trial was swifter than normal Thursday, with users of China's popular Twitter-like service Sina Weibo playing cat and mouse with censors to discuss the case, using word play to try and get around the controls. — Reuters
