ONE of the candidates in the stock exchange council election has dropped out so that the vote for her two remaining faction colleagues will be more concentrated. The withdrawal of Audrey Chow Pei-fung, a member of the so-called pro-Chim Pui-chung camp, has left six candidates vying for two seats. The seven original candidates running in constituency C could be roughly described as two camps and one independent. Ms Chow belongs to the pro-Chim Pui-chung camp headed by Syed Bokhary - a staunch supporter of Mr Chim in his legislative election. The other member of the camp is Irene So Wai-yin, managing director of Mansion House Securities. Ms Chow's move should enhance her faction's chances of securing the highest possible vote. Voting rules state that exchange members must vote for two candidates to fill the two vacancies. Fielding three candidates for the two vacancies could dilute the vote when voters decided on different combinations of two out of the three. This tactic of reducing candidate numbers is expected to be adopted by Mr Bokhary's opposition, the pro-Choi Chen Po-sum camp which also has three candidates. Mrs Choi's camp include Keith Lam Hon-keung and Au Son-yiu. Mr Lam is being widely tipped as the most likely withdrawal. The 'independent' is Lai Kwok-kuen, already a council member. The election will be held on October 27. Seven candidates are standing in constituency A.
