The head of a Preparatory Committee sub-group insisted yesterday on its right to choose election methods for the first post-handover legislature. There are fears executive councillors and provisional legislators will challenge its recommendation, which will be finalised next month. Professor Lau Siu-kai, convenor of the sub-group on the first legislature, said he was unworried by possible challenges. Post-handover executive council members have urged the committee to allow more flexibility for the Special Administrative Region government to formulate the detail of electoral methods. 'I believe some individuals will have different ideas and I know some of the provisional legislators even plan to amend our decision . . . but it is only a minority,' Professor Lau said. Liberal Party chairman Allen Lee Peng-fei urged the Preparatory Committee to give provisional legislature members more time to think about election methods. Mr Lee said: 'I know that over 15 professions want to compete for the nine functional constituency seats.' Professor Lau said that the committee should have total discretion to decide. 'We will take members' advice into account . . . but it should be the Preparatory Committee's own decision whether to fix only a framework or make detailed arrangements,' he said.
