Public satisfaction with Hong Kong’s graft-buster has plunged to a record low since 2013 and is the worst among all disciplined services, according to a survey. The University of Hong Kong’s public opinion programme released the latest statistics yesterday from a poll of 1,000 citizens conducted in late November. The findings indicated that approval ratings for the Independent Commission Against Corruption dropped from 67.3 marks to 63.2 in five months, ranking the agency at the bottom of the pack among disciplined services. Where to now for the ICAC? The score was the lowest since former chief Timothy Tong Hin-ming came under scrutiny three years ago for his lavish spending on official entertainment, gifts and duty visits. “ICAC will take the survey [findings] into reference,” an agency spokesman said. The graft-buster, however, quoted another survey conducted by an independent organisation that said 97 per cent of interviewees “support” ICAC’s work. While the HKU survey did not offer a conclusion from the findings, it came in the aftermath of a series of controversial ICAC shake-ups, including the removal of powerful operations head Rebecca Li Bo-lan from her post in July, which sparked an uproar. Successor Ricky Yau Shu-chun withdrew his resignation within hours of his departure being announced. The saga put the credibility of the agency and the leadership of commissioner Simon Peh Yun-lu into question. Meanwhile, the Fire Services Department ranked highest in the HKU survey with 83.9 marks. The overall ranking of the Immigration Department climbed up two positions to sixth, followed by the Correctional Services Department and the police force.
