Chief Executive Tung Chee-hwa has sought clarification from Beijing over allegations of threats from the mainland against radio talk-show hosts and voter intimidation. He said the central government responded that it would not do anything to undermine the 'one country, two systems' principle. A day after radio talk-show host Allen Lee Peng-fei told lawmakers that he quit the controversial Teacup in a Storm after receiving what he perceived as an intimidating phone call from a retired mainland official, Mr Tung broke his silence in an attempt to restore confidence in Hong Kong's freedom of speech. 'I have made inquiries, specifically with the relevant central authorities. They have told me that it is the staunch and fundamental policy of the central government to safeguard 'one country, two systems', Hong Kong people running Hong Kong and a high degree of autonomy,' he said. 'The central government will not do anything to undermine 'one country, two systems' and the interests of Hong Kong. The central government also supports the SAR government to take action to safeguard the freedom of expression and of the press.' This is the first time Mr Tung has commented on the controversies involving Mr Lee, Albert Cheng King-hon and Wong Yuk-man, who quit the airwaves because of alleged pressure or intimidation. Concerns over mainland officials pressuring people to vote for pro-Beijing candidates in the September Legco elections are also growing after people called the popular morning show to relate their experiences. Hours after announcing strong first-quarter economic growth, Mr Tung said a favourable atmosphere was vital to economic recovery. 'I am very concerned about the recent departure of several radio show hosts and reports of canvassing activities allegedly involving mainland authorities,' he said. 'It is the responsibility of the SAR government to protect the legal rights and personal safety of citizens.' He said he had asked the relevant departments to follow up the cases. Police Commissioner Dick Lee Ming-kwai said police had launched detailed investigations and had met the talk-show hosts, as well as people with inside knowledge of the political scene, including professors and politicians. He said there was still no evidence that the cases involved criminal intimidation or threats to personal safety. Executive Councillor Leung Chun-ying said he believed Mr Lee did not divulge the entire truth to legislators on Thursday. He urged people who felt intimidated to report their concerns to police. He said Hong Kong had increasingly become politicised and polarised, especially in the run-up to the September elections.
