A second member of Donald Tsang Yam-kuen's cabinet says the government lacks vision - a day after Executive Council convenor Leung Chun-ying's veiled attack on the administration. Cheng Yiu-tong defended Leung's remarks, saying it was an Exco member's duty to 'give advice' on government failures. In an article published in the Washington-based Hong Kong Journal on Tuesday, Leung said the government 'should be seen to build policies in a visionary way, and plan for the long term', and it should 'roll up its sleeves' to plan for the future. Cheng asked why the government had not followed the lead of former chief executive Tung Chee-hwa, who once commissioned a 'Hong Kong 2030' study on the city's long-term co-operation with the mainland. 'The special administrative region government should accelerate work in this respect,' he said. Cheng found it natural for Leung to give advice or offer criticism. 'After all, it is for the government's good.' Asked to comment on Leung's remarks, Chief Secretary Henry Tang Ying-yen said the whole team 'shares the same goals'.
