Former top official Wilson Fung has been sentenced to nine months in jail for misconduct in public office, over his acceptance of HK$510,000 from a Macau businesswoman in 2004.

He was convicted of failing to declare a conflict of interest when accepting the money from Cheyenne Chan, who was his mistress and the sister-in-law of casino mogul, Stanley Ho.

Fung was the Deputy Secretary for Economic Development and Labour when Chan’s three airline and helicopter firms applied for air traffic rights and requested an expansion of landing sites in 2004.

His wife, Betty Fung, who is the head of the government’s Policy Innovation and Co-ordination Office, was with him in court on Thursday.

Wilson Fung was acquitted last month on a charge of accepting an advantage as a public servant. Chan was also acquitted of a charge of offering an advantage to a public servant.

District Court judge Douglas Yau said it was possible that the HK$510,000 Chan gave Fung was completely unrelated to their jobs.
