Robert Chung affair

The Robert Chung affair (Chinese: 鍾庭耀事件), or Chung affair or Pollgate (Chinese: 港大民調風波; lit. 'HKU Pollster controversies'), was a Hong Kong political scandal in 2000 concerning interference with the work of Robert Chung and the Public Opinion Programme of the University of Hong Kong (HKUPOP), which he led.

Chung accused the Chief Executive, Tung Chee-hwa, of pressuring him to stop publishing the government's approval rating, in messages conveyed by the vice-chancellor and pro-vice-chancellor of the University of Hong Kong (HKU). The affair attracted public interest because it raised questions of academic freedom and because of the cooperation of university officials with the Chief Executive. An investigation panel set up by HKU held Chung's allegations to be substantiated, after which the vice-chancellor and pro-vice-chancellor resigned. Tung's closest aide Andrew Lo, however, stayed in office despite his involvement.
