At least four groups with opposing views on the national security bill are planning to rally outside the Legco building on Wednesday. Police confirmed yesterday they had received notification from the Hong Kong Island Federation, the Kowloon Federation of Association, the Civil Human Rights Front and the Falun Gong movement. The first two groups support passage of the bill, while the latter two are against it. It remains uncertain if the protest planned by the Civil Human Rights Front, which led the July 1 march, will go ahead as police have yet to approve its application. March organisers have called on the public to gather outside the Legco building in Central on Wednesday - when the bill is scheduled for second reading - if the government fails to respond to the public's demand to delay the enactment of the controversial national security laws. Yesterday, Executive Councillor and Liberal Party chairman James Tien Pei-chun urged the government to delay the enactment of the bill after discussing the issue with the central government. Despite this development, the pro-democracy camp said Wednesday's protest would go ahead as scheduled. Chan Kwok-keung, of the Federation of Trade Unions, said some members of its subsidiary unions planned to rally outside Legco to voice their support for the bill. Lee Cheuk-yan, spokesman for the Civil Human Rights Front, said everyone had a right to express their views, but he accused the pro-government camp of trying to counter opposing views. Mr Lee said front representatives met police yesterday and urged them to close roads near Chater Garden to allow more room for the expected 50,000 protesters. He also hoped that the Hong Kong Dance Federation, which has booked the whole of Chater Garden near the Legco building from June 30 to July 11 could make way for the protesters.
