Lawmakers have clashed over whether the financial secretary should be punished over the controversy surrounding his new luxury car.
Those from the opposition camp yesterday stepped up their campaign for an independent investigation of Antony Leung Kam-chung, with some calling for his removal.
But pro-government lawmakers were more sympathetic, saying the case did not warrant any harsh penalty.
The controversy erupted on Sunday after Mr Leung admitted that he had bought a $790,000 Lexus 430 only weeks ahead of increases in the vehicle registration tax announced in his Budget last week. The price of the car rose to $840,000 after the increases took effect.
Mr Leung said he needed the car to transport his new-born baby girl and family.
He later conceded he should not have bought the vehicle and that he would donate $100,000 to charity. This figure has now been raised to $380,000.
The row has prompted pro-democracy independent legislator Albert Chan Wai-yip to stage a signature campaign today calling for Mr Leung's resignation.
