Hours after announcing his resignation, Donald Tsang Yam-kuen was presented with a series of challenges from aspiring contestants in the chief executive election. Democratic Party chairman Lee Wing-tat challenged Mr Tsang to a televised debate on policies from social livelihood to constitutional reform, asked him to attend forums in at least five geographical constituencies to consult the public and to attend all election forums, whether organised by Election Committee members or others. 'If Donald accepts my challenge to a televised debate, he can pick the time and place and I'll be there,' he said. Another hopeful, Chim Pui-chung, welcomed Mr Tsang's announcement and presented him with three challenges. He called for Mr Tsang to face the public, identify his predecessor's inadequacies as well as his own, and to consolidate support from all people 'including those who are truly patriotic and love Hong Kong'. Chairman of the Democratic Alliance for Betterment of Hong Kong, Ma Lik, said Mr Tsang enjoyed obvious advantages, particularly governing experience, over others who had declared their bids for the post. 'Donald Tsang has many years of administrative experience and is a very strong candidate. But the DAB has to wait for the emergence of all other candidates before deciding who to back,' he said. Mr Ma remained non-committal on Mr Tsang's bid, saying the 130 Election Committee members from his party would meet on Monday to discuss which candidate they would nominate. Article 45 Concern Group legislator Alan Leong Kah-kit said Mr Tsang's resignation and candidacy were all expected as the result of the election was already known. 'I think the public of Hong Kong is justified to have a feeling of being excluded from the entire process because of the arrangements and I hope Donald Tsang appreciates this and will address this sense of loss of the public,' Mr Leong said. 'While this is not an election in which he has to obtain votes directly from the man on the street, I think it would be wise of him to treat this as if it were an election by universal suffrage and to engage the public.' Mr Leong said Mr Tsang's agenda should prioritise the demands for universal suffrage and he should run his government by consensus. The election, he said, was the perfect time to foster mutual trust and build this consensus. Liberal Party Chairman James Tien Pei-chun said the 34 Election Committee members from his party were waiting for Mr Tsang to outline his policy platform before deciding whether to support him.
