The pan-democratic camp must step up efforts in the social welfare sub-sector if it plans to fill half of its 40 seats on the Election Committee, the legislator representing the sector warned yesterday. Fernando Cheung Chiu-hung said the democracy camp in the sub-sector was worrying because Democratic Party chairman Lee Wing-tat last year failed to secure any of the sub-sector nominations, with Donald Tsang Yam-kuen the favoured choice to be chief executive. 'People believed the social welfare sector was traditionally a democratic stronghold, but the coming battle will be a tough one,' he said. He said the sector gave the impression it was difficult to deal with during former chief executive Tung Chee-hwa's era, but he had no idea why it suddenly threw its weight behind Mr Tsang. Mr Cheung said much effort would be needed if the pro-democracy camp was to field 20 candidates from the constituency to contest the Election Committee poll in December. But there was no guarantee these members would vote for the candidate nominated by the pro-democracy camp, he said. The camp aims to win at least 100 seats on the 800-strong Election Committee, the number required to nominate its candidate in next year's chief executive race. The sub-sector is divided between three groups - the Hong Kong Council of Social Service, Hong Kong Social Workers Association and the Hong Kong Social Workers' General Union. 'Their financial source comes from the government ... They will eventually back Tsang Yam-kuen as they dare not offend him,' Mr Cheung said. Kwai Ching District Council yesterday passed a motion supporting a government plan to allow more participation by district councils in district management. The pilot scheme will be introduced in several districts next January.
