Increasing the number of seats in the Legislative Council could broaden public participation in politics, the constitutional affairs chief said yesterday. Stephen Lam Sui-lung also said the government hoped to involve more middle-class people in its policy-making process by sticking to its guidelines on membership of advisory boards. 'Our normal practice is that an appointee's term would not exceed six years, and won't sit on more than six advisory boards at one time,' he said. But Patrick Tsang Kwong-hoi, a member of the New Century Forum, who was among a number of representatives invited to give their views on the political system, said although his name was entered into a database 10 years ago, he had never been appointed to sit on any advisory body. He was asked to join the course development committee but was later told some 'well-known figures' had filled the places. In response to the concerns of some representatives at the lack of a channel for people to take part in politics, Mr Lam said: 'If we can expand the number of seats in Legco, we can let more interested parties and individuals participate in politics.' He would enhance communication with political parties and lawmakers to work towards Hong Kong's constitutional development.
