Heated scenes were witnessed after Panneerselvam, who was replying to the debate on Budget presented by him last week, made some remarks about the scam, in which DMK leaders Kanimozhi and former Telecom Minister A Raja are accused.
The DMK members, led by their floor leader M K Stalin, vociferously opposed Panneerselvam's remarks and wanted the Speaker P Dhanapal to expunge the remark.
However, Dhanapal did not heed to their demand, prompting the DMK legislators to troupe out of the House.
Seeking to rub salt into DMK's wounds, Pannneerselvam said that his government had not been dragged to the court over any findings by the CAG, in an apparent reference to Kanimozhi and Raja attending court hearings in this matter.
