Hundreds of people yesterday signed a petition asking Mr Leung to apologise for buying his new car ahead of announcing tax increases for luxury vehicles.
In just 2.5 hours, more than 400 people put their names to the petition in Central. The signature campaign will continue in the next few days throughout Hong Kong.
The petition called on Mr Leung to make a public apology for his involvement in the incident, and called for the Legislative Council and the Independent Commission Against Corruption to investigate.
Some of those who signed questioned Mr Leung's integrity as a minister of Chief Executive Tung Chee-hwa's cabinet, and accused him of breaching rules preventing a conflict of interest. Mr Leung is to donate $380,000 to charity after it was revealed that he had bought a Lexus 430 ahead of the Budget. He effectively paid $50,000 less than he would have before the Budget details were announced.
Mr Tung has criticised Mr Leung for being negligent and acting inappropriately over the incident.
The Legco constitutional affairs panel is to discuss the controversy on Monday at a meeting which Mr Leung has promised to attend.
