They condemn the threats to activist Winston Chu and demand more consultation Four organisations yesterday called on the public to support a demonstration on Sunday that seeks to highlight the need to preserve Victoria Harbour. The rally comes after activist Winston Chu Ka-sun said he was leaving Hong Kong because of death threats to him and his family. He also resigned as chairman of the Society for the Protection of the Harbour. The four groups issued a joint declaration condemning the threats to Mr Chu, who had led the campaign to oppose the government's reclamation plans. The Action Group on the Protection of the Harbour, the Society for the Protection of the Harbour, SynergyNet and Greenpeace asked supporters to don blue T-shirts and ribbons to attend the rally, which will start at 11am at Edinburgh Place in Central. The organisers plan to lead a march to government headquarters. The groups asked the government to consider another round of public consultation on its plans for the harbour. They also demanded that all reclamation work cease until the courts finally decide on their legality. Kwok Ka-ki, a convenor of the Action Group, said he believed the anti-reclamation campaign would not lose its momentum. 'It's not just Mr Chu's issue. It's everyone's issue. Our group is trying to figure out whether it is possible to get Victoria Harbour put on the United Nations' heritage list to ensure that it will be well preserved,' he said. SynergyNet head Anthony Cheung Bing-leung said that if the people who threatened Mr Chu wanted to stop the campaign to protect the harbour, their plan had backfired.
