University of Hong Kong students have voted with a significant majority to support a motion calling on Beijing to vindicate the 1989 democratic movement and be held accountable for the June 4 crackdown. Of the 1,991 valid votes, 1,843 votes - or 92.6 per cent - backed the motion, with 79 against it and 69 abstentions. A total of 2,004 students cast their votes, accounting for 19 per cent of the 10,500 members of the students' union, which had tabled the motion. The motion demands that the central government deliver a public apology and offer compensation to the families of those who were killed. It also calls for the release of all dissidents still detained because of their roles in the massive protests. The outcome of the three-day polling becomes the permanent stance of the students' union on the June 4 crackdown. Earlier yesterday, union president Ayo Chan Yi-ngok insisted on staying on despite facing a possible vote of no confidence over his controversial remarks on the Tiananmen incident. 'Resignation could mean I indirectly admit that my previous remarks were wrong,' Mr Chan said. 'My way to express my opinions may not be perfect, but I persist in my words.' He reiterated support for a vindication of the June 4 incident and urged Beijing to disclose the truth. More than a week ago, he criticised some student leaders in the crackdown as 'runaway student leaders' and said military suppression could have been avoided had demonstrators dispersed peacefully. The union council is examining a motion, moved by postgraduate student Christina Chan Hau-man, to dismiss Mr Chan by initiating a campus referendum. Seven former union presidents and 20 former union members launched an online 'Oust Ayo Chan Yi-ngok' campaign. The former students said in a joint statement that they were 'sickened by Chan's remarks', which they said had 'distorted history'. 'We cannot judge whether Chan simply lacks knowledge of history, or if he is trying to flatter the ones in power,' the statement read. 'But we are certain that his comments reflect his inability to tell black from white.' Gloria Chang Wan-ki, who was elected union president in 2000, was one of those who signed the statement. She said holding a referendum would be the best way to resolve controversy and to avoid emotional criticism of Mr Chan.
