Senior members of Singapore’s business, political and legal elite have backed fresh attempts to overturn the colonial-era section of the country’s penal code that criminalizes gay sex. Leading the push are former ambassador to the U.S. Tommy Koh, former attorney general Walter Woon, Banyan Tree Holdings Ltd. founder and executive chairman Ho Kwon Ping, National University of Singapore board chairman Hsieh Fu Hua, and Shangri-La Hotel Ltd executive chairman Kay Kuok.
