Officials last night appeared to be heading for a tough fight to block a legislators' no-confidence vote in two top housing chiefs. This was despite the resignation of one - Housing Authority chairwoman Rosanna Wong Yick-ming - ahead of the debate. After an urgent meeting on Ms Wong's resignation, Liberal Party chairman James Tien Pei-chun said the party had stuck to its support for the motion, which could be moved by Democrat Fred Li Wah-ming as early as today. Of the 10 Liberals, six are set to join the Democrats and the Democratic Alliance for the Betterment of Hong Kong members in backing the no-confidence vote. Of the other four, Ho Sai-chu and Selina Chow Liang Shuk-yee would not join the debate or vote. Mr Ho is an authority member and Mrs Chow's husband, Joseph Chow Ming-kuen, is a former member. The voting intentions of Ronald Arculli and Lau Wong-fat remained unclear. The Liberals' support for the motion is crucial following signs more non-affiliated legislators would either oppose or abstain from the Democrat motion after Ms Wong resigned on Saturday. Mr Li was delighted with the Liberal Party's support. He compared his motion's chances to the Hang Seng Index. 'There are lots of ups and downs. It's now going up a bit. I hope to persuade more independents to support me in the run-up to the vote. It will be a pretty close vote,' he said. The motion needs at least 15 votes from each of two groups - the 30 legislators returned via geographical polls and the election committee and those from functional constituencies. Mr Tien said: 'We feel that a majority of the problem has been resolved [following Ms Wong's resignation]. I can't see any reasons why we should change our stance.' Eric Li Ka-cheung, non-affiliated legislator and convenor of the 'Breakfast Group', said 11 non-affiliated members had informally discussed the motion again but views were still divided. Non-affiliated Ng Leung-sing, who will oppose the motion, said he and six other authority committee chairmen planned to write to members to explain why the motion would not solve the problem of building quality. Ambrose Lau Hon-chuen, chairman of the Hong Kong Progressive Alliance, said the motion had become 'meaningless' following Ms Wong's resignation. Party colleague Choy So-yuk, who earlier indicated her support for the motion, will reconsider. Dr Tang Siu-tong is set to deviate from the alliance's stance and vote in favour of Mr Li's motion. Raymond Ho Chung-tai, non-affiliated legislator representing the engineering sector, said he had started a third round of consultations on his electorate's views and would vote in accordance with constituents' views. Tsang Yok-sing, chairman of the Democratic Alliance for the Betterment of Hong Kong, said he would find it difficult to back the motion if Mr Li deleted Ms Wong's name from it. The party has 10 Legco representatives. He said his party would continue to back the motion.
