A vote for the DAB would be a vote for Gary Cheng, Democratic Party heavyweight Szeto Wah said yesterday. Mr Szeto, the party whip, called on voters to give the Democrats their full support in the election to curtail the culture of shoe-shining and abuse of power for personal gain. In an election programme on Metro News, Mr Cheng's scandal was the focus of attacks by rivals in Kowloon East of the Democratic Alliance for the Betterment of Hong Kong. Mr Szeto, who heads the Democrat list, attacked Mr Cheng for saying the DAB should decide whether he should resign if elected. 'Although he has quit his party vice-chairmanship, he has not committed himself to giving up his seat if elected,' Mr Szeto said. 'Is he accountable only to his party and not the public?' The veteran politician claimed the DAB was deceiving voters by urging them to focus on Choy So-yuk, who is ranked second on the DAB's Island constituency list, behind Mr Cheng. DAB chairman Tsang Yok-sing called on the public to vote for Ms Choy if they were unhappy with Mr Cheng. Under the electoral system, the first-ranked candidate is elected if the list only receives enough votes for one seat. Mr Szeto also accused Mr Cheng of asking for preferential treatment from Baptist University for his girlfriend, Zhang Zhuan. Mr Cheng wrote to university president Dr Daniel Tse Chi-wai in May in support of Ms Zhang's application for a master's degree course in mass communications. 'Outside the enrolment period and [with Ms Zhang] taking no examination, Mr Cheng was obviously seeking private privileges when he made the recommendation on behalf of his girlfriend, who was having an extramarital affair with him. Another major reason may be he wanted her to come to Hong Kong to stay with him,' Mr Szeto said. Chan Yuen-han, who heads the DAB list in Kowloon East, said voters were mature enough to decide whether to support the party. But she conceded the party should learn from Mr Cheng's scandal. 'All public figures have to be accountable to the public. I agree to the need for an inquiry into the incident so we can discuss it openly,' Ms Chan said. Separately, Executive Council convenor Leung Chun-ying declined to say if Legco should carry out an investigation into the scandal. 'I think it is a matter for Legco,' Mr Leung said.
