ABOUT 500 people have already signed up as founding members of the Democratic Party, resulting from the merger of the United Democrats and Meeting Point to take place on October 2. Last night, Meeting Point chairman Anthony Cheung Bing-leung said the membership was expected to grow, as many who had indicated their willingness to join had yet to register. Speaking after the last meeting of the merging committee last night, Mr Cheung said the new party would comprise a 30-strong central committee, including a chairman and two vice-chairmen. A 15-strong current affairs committee will be set up directly under the central committee to oversee the party's stance on macro-political developments. Four branches - organising, policy, political affairs and elections - will deal with the daily operation of the party. A disciplinary committee, comprising 10 members, will become the internal monitoring organ. The party logo, which has yet to receive the final touches from artists, will depict a white pigeon, in flight, on a green background. Mr Cheung said the logo symbolised the vitality and energy of the new party. He rejected suggestions that it was too like the United Democrats of Hong Kong (UDHK) logo, which also carried a pigeon. It is understood UDHK chief Martin Lee Chu-ming will run for the chairmanship, while Mr Cheung and UDHK vice-chairman Yeung Sum will contest the two places for vice-chairmen. Mr Cheung said he preferred the party chairman to be a Legislative Councillor. 'In this way, he can respond quicker to events on the political scene, as he's better informed,' he said.
