Chief Executive Donald Tsang Yam-kuen has been urged to gauge Beijing's bottom line on the implementation of universal suffrage in 2012 during his forthcoming visit to the capital. The call from pan-democrats came as Mr Tsang prepared to fly to the capital tomorrow for a three-day visit, during which he will meet state leaders. The purpose of his visit is to receive the formal letter appointing him chief executive from July 1. A government source said Mr Tsang would explain his policy priorities for his next administration to state leaders. Mr Tsang is expected to urge state leaders to help strengthen Hong Kong's role as a financial centre over the next five years. A source in the Beijing loyalist camp said Mr Tsang would also reveal to the central government his candidates for the key posts of chief secretary and financial secretary. This source said he expected the names of Mr Tsang's new cabinet would be released in June. Albert Ho Chun-yan, Democratic Party chairman, and Lee Cheuk-yan, a unionist, urged Mr Tsang to relay the aspirations of Hong Kong people for universal suffrage in 2012 to state leaders during his visit to Beijing. They said the people of Hong Kong wanted direct elections for the chief executive and the legislative body by then. 'Mr Tsang should listen to Hong Kong people on what they want and fight for us, not only side with Beijing on the matter of constitutional reform,' said Mr Lee. Mr Ho and Mr Lee believe Mr Tsang should test the bottom line on universal suffrage with state leaders during his visit. 'He said he would find a solution for this issue within his term. However, we are afraid that the proposals he suggested might not be accepted by Hong Kong people,' Mr Ho said. He expects the proposals to be conservative rather than liberal. The pan-democratic camp will launch a signature campaign in Causeway Bay on Monday to gather public support for pursuing the implementation of universal suffrage in 2012. The chief executive says a green paper contain three proposals for achieving universal suffrage will be issued mid-year. He forecasts that a 'final solution' to be submitted to Beijing will have the support of 60 per cent of Hong Kong people. The chief executive has no plan to visit any ministry or department in Beijing; he met the heads of at least 10 ministries during his last duty visit. Mr Tsang will spend the last day of his visit touring the National Stadium - the venue for the opening ceremony of the Olympics - as well as the Palace and Capital museums. The government source said the places on Mr Tsang's programme were all related to the 2008 Games and the 10th anniversary of Hong Kong's return to China. The Palace Museum will send Chinese paintings and calligraphy to Hong Kong for an exhibition in June as part of handover anniversary celebrations.
