The party's chief spokesperson Manish Sisodia took part in the protest on the 28th anniversary of the gas tragedy and said if voted to power, the party will make a law which will put guilty corporations and their officials responsible for the tragedy behind the bars.
"I think the push for attracting foreign investments is acting as a deterrent in taking strong action against the accused comapany and the politicians," Sisodia told reporters.
The Bhopal gas tragedy in December 1984, the world's worst industrial disaster, killed thousands of people, with several lakhs still suffering from the lethal consequences of the gas leak.
The protesters demanded Prime Minister Manmohan Singh's intervention to punish the guilty corporations and their officials and adequately compensate all victims. (more)
