Government allies are planning to repeat their 2005 strategy to drum up support for the constitutional-reform proposal through a massive signature campaign - this time in collaboration with pro-government media organisations. The move by a newly formed alliance, which counts more than 100 leading tycoons, politicians and professionals among its ranks, came as pan-democrats moved ahead with their plan to resign and trigger a de facto referendum on universal suffrage. Some Civic Party leaders were expressing worries about rumours that party leader Audrey Eu Yuet-mee would be one of the lawmakers to resign her seat. Launching the Alliance for Constitutional Development, executive councillor Cheng Yiu-tong, of the Federation of Trade Unions, said he hoped the new group would reflect the public consensus that the electoral system for the 2012 chief executive and Legislative Council elections should move forward. 'We are totally opposed to someone who wants to close their eyes and reject the government proposal without even knowing the details,' Cheng said, referring to the pan-democrats. 'We don't care about [whether universal suffrage is introduced] in 2017 or 2047. At least we have to move forward in 2012.' Cheng said a growing number of business chambers and social groups were joining the alliance. Those who have signed up as founders include Executive Council convenor Leung Chun-ying, tipped as a front-runner for the chief executive race in 2012; tycoons Peter Woo Kwong-ching and Vincent Lo Hong-shui; former Liberal Party chairman James Tien Pei-chun and his brother Michael Tien Puk-sun; and former top officials Arthur Li Kwok-cheung and David Lan Hong-tsung. In 2005, a coalition of 11 pro-government groups led by Cheng claimed to have collected 775,000 signatures supporting the administration's reform proposal, which was vetoed by pan-democrats. This time, Cheung says the alliance will encourage the public to sign an online petition and send submissions to the government to declare their support. Three pro-government newspapers - Ta Kung Pao, Wen Wei Po and Sing Tao Daily - will receive signatures on their websites. The publicity offensive by government allies came as the Civic Party and League of Social Democrats intensified preparations for their resignation plan, in which one lawmaker from each of the five geographical constituencies will quit, then contest the ensuing by-election - creating a de facto referendum. Issuing its free newspaper, A45, the Civic Party said the scheme would allow the public to demand the abolition of Legco's functional constituencies, and a road map for genuine universal suffrage. The paper also drums up support for Alan Leong Kah-kit and Tanya Chan, who are expected to resign. But some party leaders privately expressed concerns about rumours that Eu would resign instead of Chan. They feared forces outside the party were trying to undermine Chan's image; some say her election victory last year was due to public support for Eu, her running mate. The resignations are expected next month.
