Barry Cheung held in the highest regard, before the downfall of HKMEx

He was once named the best public servant by the government's No 2 official, but until Saturday the public knew little about Barry Cheung Chun-yuen.
"He is not even one of the best. He is the best," Chief Secretary Carrie Lam Cheng Yuet-ngor told a Chinese-language newspaper in an interview three years ago.
Lam, then development chief, was reviewing urban renewal strategy with Cheung, chairman of the Urban Renewal Authority (URA). Their similar working style - both are relatively open-minded and capable of delivering on policies - made the comment unsurprising.
Cheung has been involved in a vast range of public services, from advising on civil servants' salaries to the city's long-term development strategy.
But he was seldom in the spotlight until the weekend, when the Hong Kong Mercantile Exchange, which he founded, was forced to give up its trading licence and became the subject of a police investigation over allegations of fraud.
Cheung, who grew up in the pro-Taiwan enclave of Tiu Keng Leng, received his tertiary education in mathematics in the United States, and holds an MBA from Harvard Business School.
