A member of University of Hong Kong's governing body - a vocal critic of the outgoing vice chancellor's ability - now says Tsui Lap-chee should stay on until a successor is found. Linus Cheung Wing-lam believes Tsui should be given an extension to his contract when it expires next August, according to another council member who spoke to him. Cheung told the fellow member that after 'long deliberation', he agreed Tsui's contract should be extended for 18 months so the university could have enough time to identify a suitable successor. This volte-face comes as doubts mount as to the chances of the university replacing Tsui before August. In a shock announcement last week, Tsui said he would not be seeking a third term when his contract expires, presenting the prestigeous institution with a leadership crisis. Tsui later said he was willing to stay on until a successor was found. The council will host a special meeting on Monday to discuss whether to accept Tsui's offer to stay on. Some council members earlier said he should leave when his contract expires. Cheung, board chairman of HKU's School of Professional and Continuing Education, has been a vocal critic of Tsui, saying he lacked management ability. 'He was judging [Tsui] from the point of view of a businessman,' said the council member. 'It's sometimes different from what an academic would do.' Cheung is a well-known manager who has worked for many big companies, including PCCW and Cathay Pacific. He could not be reached for comment yesterday. Tsui has been criticised for his handling of Vice-Premier Li Keqiang's visit to HKU in September. Some accused him of turning a blind eye to the police's heavy-handed approach in dealing with protesters. The university subsequently set up a review panel to look into what went wrong on the day. According to a letter sent out from the school's communications office to HKU students this week, the panel will soon invite Tsui and council chairman Leong Che-hung to take part in 'interviews' in order to 'find facts'. Samuel Li Shing-hong, a student detained by police during Li's visit, welcomed the move to question Tsui and Leong, saying the school's decision-makers have a responsibility to reveal the truth. He urged them to release their report as soon as possible. Meanwhile, Independent Police Complaints Council chairman Jat Sew-Tong said yesterday it had yet to complete its investigation into the incident. Among 16 complaints lodged against the police over the treatment of protesters during Li's visit, investigations into seven cases have been completed. He said findings from the investigations would be released in due course.
