CANDIDATES contesting the nine new functional constituencies say they are facing immense campaign difficulties because major companies have forbidden the display of posters on their premises. Large corporations including the MTR, Kowloon Canton Railway (KCR) and major supermarket chains have said they do not allow electioneering in areas they manage. However MTR's assistant public relations manager Claudia Ho Sin-ka said candidates could rent advertising space inside MTR stations for their posters. Both the MTR and KCR conceded they could do little to prevent candidates canvassing votes near the exits of stations. A Park'N Shop spokesman said candidates could neither electioneer nor display posters inside supermarkets because the company did not want to be seen to be favouring particular candidates. Wellcome blamed limited space for its ban on election posters. What space it does have is for promotion of merchandise. Ip Kwok-fun, contesting the Transport and Communication functional constituency, said the bans prevented candidates from reaching thousands of potential voters working in the companies. The only way for candidates to keep in touch with voters was through the free mail service provided by the Government. But he doubted voters could make decisions with so little information available to them. 'This will only drive down the turnout rate as many voters may choose not to vote as they know little about the hopefuls,' Mr Ip said. Candidates contesting the Community, Social and Personal Services slot have fared somewhat better. The Government is allowing candidates to put up posters and hand out pamphlets in government buildings.
