The hit TV show Who Wants To Be a Millionaire? courted controversy last night by giving 'Taiwan' as the answer to a question on which was the biggest island in China. 'Re-unification should not take place on ATV,' complained viewer Luisa Tamm, who is from Taiwan but lives in Hong Kong. 'They shouldn't just slip a political thing like that in there. I was emotionally angry with it.' The programme's answers were regarded as gospel, used as a source of family education and discussed the next day, Ms Tamm said. A station spokesman said he did not wish to comment on the political implications of the question. 'We think it's correct that Taiwan is the biggest island of China,' he said. Questions were checked by a board including a senior executive, production staff, the programme director and consultants, he said. The show can be picked up in parts of the mainland. The television station's complaints hotline was on answering machine when called by the Post last night. The ATV spokesman said it was unable to provide details on customer complaints at that time. Both ATV and TVB were accused of self-censorship for deciding in June to refer to Chen Shui-bian as 'Taiwan leader' rather than 'Taiwan President'. ATV's deputy head of news, Tong Tak-chuen, had defended the shift, saying if the station practised self-censorship it would not report any news about Taiwan, adding ATV advocated the 'One China' principle.
