Chief Executive Tung Chee-hwa yesterday rejected calls for him to send a representative to attend a public policy forum on Sunday to be hosted by 31 Election Committee members from the pro-democracy camp. Mr Tung's election office said that as the candidate in the chief executive poll he had to directly express his views on his future administration. 'He can't be replaced by any representatives,' the election office said in a reply to Democrat Anthony Cheung Bing-leung of City University and non-affiliated legislator Audrey Eu Yuet-mee. 'In order to be equal to all, it was impossible for Mr Tung Chee-hwa to accept invitations selectively . . . The decision has nothing to do with the stance or inclination of the organisation,' the letter reads. Professor Cheung requested last week that Mr Tung send a representative to the forum after the Chief Executive declined an offer to attend in person. Peter Chua, president of the Association of Hong Kong Health Care Professionals, who met Mr Tung with other representatives of the health services sector yesterday, criticised legislator Mak Kwok-fung, who represents the sector, for joining a dump-Tung group without first consulting the views of the sector. But Mr Mak dismissed the criticism as groundless, saying that when he stood for election he made it clear he was a democrat.
