March organisers say a million people could join them next week, putting them at odds with Article 23 supporters Activists warn there could be clashes with supporters of Article 23 when they besiege the Legislative Council on the day the national security legislation is put to a vote. The Civil Human Rights Front, which organised Tuesday's 500,000-strong march, said yesterday that up to one million protesters could join the Legco action on Wednesday. Front spokesman Lee Cheuk-yan said opponents of the legislation were left with no other choice because the government had failed to respond to people's demands despite Tuesday's large turnout. While Chief Executive Tung Chee-hwa said on Tuesday that he was 'very concerned' about the mass protest and understood the people's aspirations, Mr Lee said these were empty words which failed to address the concerns of Hong Kong people. 'We will definitely besiege the Legco building on July 9. If they don't shelve the bill, our actions will continue. We will certainly lose out in Legco because of the dominance of the pro-government camp,' he said. Mr Lee said that police were notified on Monday about the front's plans for the Legco demonstration. While he admitted it was hard to estimate how many people would join the protest, Mr Lee said 'miracles' sometimes happened - a reference to the half-million people who hit the streets on Tuesday. 'If each one brings one more person, it will add up to one million people,' Mr Lee said. However, Mr Lee warned of the possibility of clashes at the protest as supporters of the national security legislation could also be present at the standoff. The head of the Catholic Church in Hong Kong, Bishop Joseph Zen Ze-kiun, urged followers not to attend out of concerns the situation would be chaotic. But he asked the government to listen to the views of the people. The main problem organisers will face is the lack of gathering space. At about the same time on Wednesday, the Hong Kong Dance Federation will be holding a performance in Chater Garden near Legco, leaving protesters without a place to assemble. A spokeswoman for the Home Affairs Bureau said the 'Dance, Dance' activity was part of the relaunch Hong Kong campaign and the federation had booked the venue from June 30 to July 11. However, she said officials would meet the federation to discuss whether it could make way for the expected large turnout. Police Commissioner Tsang Yam-pui yesterday said the large number of people at Tuesday's march was unexpected and police had tried their best to ensure that the event ran smoothly. 'There were too many people [joining the march] and Victoria Park couldn't cater for so many people and many had to wait at nearby places,' Mr Tsang said. He added that organisers should conduct a review of the march to seek improvements in the future. He also said the 1,300 police deployed for crowd control were sufficient. 'The most important thing is road arrangements,' he said. Regarding the July 9 gathering, Mr Tsang urged organisers to inform the police about their plans as soon as possible so that the necessary arrangements could be made. March organiser Richard Tsoi Yiu-cheong admitted some mistakes were made in crowd-control measures and a review would be conducted today. But he also criticised a police failure to cordon off some roads near Victoria Park, which led to people being trapped in certain areas, forcing many to wait for hours before they could join the procession. 'I'm touched that many people were eager to wait at Victoria Park because they wanted to be counted,' Mr Tsoi said.
