Activists opposed to the high-speed cross-border rail project are mobilising about 1,000 protesters to surround the Legislative Council building on Friday as a final attempt to block its funding.
Legco's Finance Committee is expected to approve HK$66.9 billion for the Guangzhou-Shenzhen-Hong Kong Express Link - including a contingency fund and compensation for land owners.
Polytechnic University associate professor Ho Chi-kwan, one of the activists, said the government had failed to clear doubts about the link.
'It is a huge amount of money,' she said. 'The government has given no explanation on how the estimated passenger flow is calculated.'
Social welfare sector legislator Peter Cheung Kwok-che said the government should spend the money on helping the poor.
