More than one-third of people surveyed say Anson Chan Fang On-sang's by-election campaign has increased their concern about political reform. The study, commissioned by the pan-democrats, also found 67 per cent of the 1,027 respondents said the government should draft several proposals to consult the public again. With the green paper consultation on political reform ending in two weeks, 35 per cent said it had been conducted poorly. Only 18 per cent gave their approval, while 30 per cent gave a 'half-half' response, the study by the public opinion programme of the University of Hong Kong found. Asked what should happen if there was no proposal that could win majority public support, 62 per cent said the administration should then consult the public again. Twenty-eight per cent said the government should submit a proposal for the Legislative Council to decide. Pollster Robert Chung Ting-yiu said the findings showed most people wanted the government to carry out its consultation well in order to secure public consensus. On Mrs Chan's Legco campaign, 37 per cent said it had raised their concerns about reform, while 56 per cent said there had been no effect. Dr Chung said: 'Mrs Chan's participation in the contest seems to have had a certain positive effect.' Support for the pan-democrats' universal suffrage model for chief executive and Legco polls in 2012 remained stable at more than 50 per cent, he added.
