Lawmakers of the League of Social Democrats are expected to hit out again at Chief Executive Donald Tsang Yam-kuen when he visits the Legislative Council on Thursday for a question-and-answer session. On top of the likely onslaught by the maverick lawmakers, Mr Tsang is expected to be grilled on issues of democratisation and jobs as he briefs the legislature on his thoughts about the downturn. Wong Yuk-man, the leader of the league who threw a bunch of bananas at Mr Tsang in October during his last visit, said he had already planned a surprise for him. 'I can assure you that there will be a good show. Among other things, we will call for his resignation because he is losing his grip on governance, as he really is impotent in his administration,' Mr Wong said. Chief Secretary Henry Tang Ying-yen - who wrote a complaint letter to Legco president Tsang Yok-sing last week on the attitude of the league trio during an earlier meeting - could also be a target. Mr Wong said: 'Henry Tang was trying to pick a fight against the LSD by protecting Donald Tsang's cronies because he wants to become the next chief executive. We will not rule out radical action against him, too.' Last night a government spokesman said officials expected to be protected from offensive and insulting language. 'The community also expects rational debates in the Legco chamber,' he said. The three lawmakers, Leung Kwok-hung, Albert Chan Wai-yip and Mr Wong, were expelled during a meeting last week when they hurled abuse at the minister for constitutional affairs, Stephen Lam Sui-lung. They accused him of defending the government's slow progress in introducing universal suffrage. A government source said that while there would be no need to step up police security to protect Mr Tsang from physical harm, the chief executive was 'psychologically prepared' for any surprises. The source said Mr Tsang was unlikely to announce any initiative to stimulate the economy because details would be announced by Financial Secretary John Tsang Chun-wah in next month's budget, but he would focus his thoughts on the economy. Other political parties said they would question Mr Tsang on issues like constitutional reform and problems such as unemployment. Audrey Eu Yuet-mee, leader of the Civic Party, said it planned to focus on the failure of Mr Tsang's governance on universal suffrage, the environment and the economy. Democratic Party vice-chairwoman Emily Lau Wai-hing said that on top of grilling Mr Tsang about the lack of progress on democratisation, her party would demand swifter action to help victims of Lehman Brothers minibonds. 'The victims have been waiting long enough and their patience is wearing thin,' she said. The Federation of Trade Unions said it would ask Mr Tsang for measures to help lower the jobless rate.
