Chief Executive Donald Tsang Yam-kuen has condemned radical actions against government officials, saying such 'barbaric acts' would obstruct communications between government and community. Responding to a protest on Thursday before a district council meeting in Sha Tin, he said he would expect such demonstrations to be held in an orderly, peaceful and legal manner. Secretary for Constitutional and Mainland Affairs Stephen Lam Sui-lung was mobbed by a group of pro-democracy protesters when he arrived for the meeting, and camphor balls were thrown at him by legislator 'Long Hair' Leung Kwok-hung, who accused him of muddying the waters on political reform. Mr Tsang said the government had absolute respect for freedom of expression, but the demonstrators could not overstep the mark. 'I cannot accept those radical ideas, including the use of language, violence or threatening means towards officials. Those barbaric acts, if tolerated, will hamper the dialogue between the government and the community,' he said. Mr Lam's schedule for presenting the green paper on political reform to district councillors was not affected, and he appeared at another briefing yesterday in Sai Kung. Sai Kung district councillors followed their colleagues in Sha Tin in passing a motion calling for the chief executive to be elected by universal suffrage not later than 2017, and all legislators to be directly elected at a later date. Meanwhile, Mr Lam said new posts for deputy secretaries and ministers' assistants, to be advertised later in the year, would be open only to those who shared the chief executive's views.
