Confidence in Hong Kong's press freedom is at its lowest in four years following the abrupt departure of two outspoken radio talk-show hosts, a survey has found. Twenty-three per cent of respondents said they were dissatisfied with press freedom in Hong Kong, compared with 12 per cent in a survey conducted last month. The poll of 1,021 people was carried out by the University of Hong Kong's public opinion programme between May 10 and last Thursday. The dissatisfaction rate was the highest since the survey started in January 2000. The previous highest, recorded in May 2001, was just above 21 per cent. In the latest survey, 51 per cent of respondents said they were satisfied with press freedom, a drop of eight points from last month's poll. About 23 per cent gave their satisfaction rate as 'half-half', while 3 per cent said they did not know. Last Thursday, radio talk-show host Raymond Wong Yuk-man announced an abrupt halt to his decade-long broadcasting career. Without specifying the reasons, Wong, who was assaulted in Tsim Sha Tsui in March, said he needed to take a break. The resignation of Wong, noted for his anti-communist stance and fierce criticism of both the Hong Kong and central governments, followed that of Albert Cheng King-hon, his Commercial Radio colleague who quit last month after receiving death threats.
