The pro-business Liberal Party yesterday threw its weight behind Donald Tsang Yam-kuen's bid for chief executive - pledging to supply up to 100 nominations. It followed party leaders' discussions with Mr Tsang about their future roles in a ruling coalition. The pledge of support came as five legislators from The Alliance, which represents several professional sectors, said more than a dozen of its electors would back Mr Tsang in recognition of his administrative ability. Speaking after meeting fellow members, Liberal Party chairman James Tien Pei-chun said the leadership had decided to pledge the party's 30 votes to Mr Tsang, and would lobby others to nominate Mr Tsang. 'Although Mr Tsang has yet to come up with a platform, the Liberal Party approves of Mr Tsang's administrative abilities shown during his years as financial secretary and chief secretary,' Mr Tien said. He said that during talks with Mr Tsang, they discussed how to improve co-operation between the government and pro-government parties should Mr Tsang be elected. He said Mr Tsang promised to review the situation under Tung Chee-hwa's administration, which the Liberal Party had criticised as an 'unfair deal'. Although the party had a representative in the Executive Council, it did not have much direct input into policymaking and was required to back government proposals in Legco, he said. 'There is a need for the government to listen more to the friendly political party which is part of the ruling coalition. Otherwise, why should we stand up for [the government in Legco]? 'Mr Tsang promised to address the problem ... He felt the previous situation was not perfect. I think this represents a great step forward,' he said, while denying that Mr Tsang made the concession in exchange for the Liberals' support. He said the party's decision was in line with the views of members of various sectors represented by the party and an opinion poll result. More than 70 per cent of the 2,800 respondents said they supported Mr Tsang, Mr Tien said. He said his party would mobilise support to seek nominations among the 800-member Election Committee for Mr Tsang. Mr Tien said up to 100 nominations could come from sectors including tourism, textile, catering and retailing.
