The Democratic Alliance for the Betterment of Hong Kong decided last night to issue a set of guidelines governing members' conduct, including investment activities. But Ma Lik, chairman of the DAB's Disciplinary Committee, said that no public apology would be made over the incident in which members sought to buy shares in the new Kwong On Bank. No disciplinary actions would be taken against the two members who had attempted to buy the shares. 'The fault lay with the Central Committee because it had not issued guidelines for members,' said Mr Ma. 'We don't think the matter can be solved just by making an apology. It would be more helpful to draft guidelines for members.' Mr Ma said that there was no need for an apology because the DAB councillors had not lied about the matter. At the party's Central Committee meeting, it was decided that the Disciplinary Committee would draft a set of guidelines for the Committee's scrutiny within a month. The guidelines are expected to be of benefit all members.
