Former chief executive Tung Chee-hwa has urged pan-democratic lawmakers to "unbundle" their united stance in blocking the government's reform plan, whose passage he says will help mend a political rift in society. He spoke a week ahead of the Legislative Council's scrutiny of the blueprint for the 2017 chief executive election, which all 27 pan-democratic lawmakers had vowed to vote down. Tung, now vice-chairman of the Chinese People's Political Consultative Conference, criticised the pan-democrats for aligning their voting preferences, which he called "undemocratic". "You can bundle a vote, but you cannot bundle idealism, you cannot bundle your own belief," Tung told the Our Hong Kong Foundation, a think tank he founded in November. "I would like to appeal to you - at this very crucial time - to unbundle yourself, to let everybody vote according to their conscience." Approval of the reform plan would bring an end to the city's "internal bickering" and help the administration regain authority in advocating policies, he said. Basic Law Committee vice-chairwoman Elsie Leung Oi-sie, meanwhile, looked beyond the expected collapse of the blueprint in Legco, urging the city instead to put aside debate about electoral reform if it failed. The pan-democrats should in any case improve ties with Beijing and should not communicate only "amid a war", she said on an online show hosted by Democratic Party chairwoman Emily Lau Wai-hing. The former justice secretary's views were shared by Chief Secretary Carrie Lam Cheng Yuet-ngor, whom accountancy-sector lawmaker Kenneth Leung cited as telling the pan-democrats the administration would not restart the reform process before its tenure ended in 2017. Separately, the Institute of Architects, Institute of Landscape Architects, Institute of Planners and Institute of Surveyors each polled their members about the proposed reform. Almost half of the 3,104 people polled from May 19 to June 3 supported the proposal, while 45.8 per cent were against it and 2.5 per cent had no opinion.
