Professor Lau Siu-kai, the head of the Central Policy Unit and the government's chief adviser, said the unit had conducted three surveys since the resignation, all of which consistently showed that more than half the 1,000 respondents polled opposed the 'referendum' campaign. Campaign organisers rejected Lau's claim, saying he famously underestimated attendance at the on 1 July 2003 protest march at 30,000.
