Officials yesterday bowed to pressure from legislators by agreeing to brief them on the role and function of the new police Security Wing. The U-turn came after Legco security panel chairman James To Kun-sun vowed to block funding for the wing, comprising 456 officers, in this year's Budget if the Government declined to reveal more details. Mr To and his colleagues were angered when Secretary for Security Peter Lai Hing-ling last week refused to say any more than that the wing's duties were internal security. He said the Government took a strong view that the wing's activities should be kept secret. But a spokesman from the Security Branch said yesterday the Government had been considering Legco's demand for more information and had decided to brief members next month. The Legco Secretariat had been informed and a convenient date and time was being worked out. He urged Legco members not to amend the Budget. The exact figure for funds set aside for the new wing is not known. Legco members will debate the Budget tomorrow and on Thursday and will cast their votes next week. Mr To said he wanted the briefing before the Budget vote. He said he would decide whether to press ahead with his amendment after the briefing. 'I do not want to commit to anything before the briefing session,' he said. He tabled an amendment, seeking to cut $110 million in police funding, yesterday. He acknowledged the need to keep the meeting confidential and said the meeting should be held in police headquarters.
