The Congress on Tuesday attacked the NDA government and accused it of failure to take action against those allegedly involved in corruption.“What action have they taken against the son of Chhattisgarh Chief Minister? What about the cases against the Rajasthan Chief Minister? What has happened to the inquiry on Lalit Modi? Why haven't they dismissed Eknath Khadse, their minister in Maharashtra who is facing allegations of land grabbing,” said senior Congress leader Anand Sharma while addressing a press conference here. “They have levelled enough allegations. We pose an open challenge to this government to release the list of names of Congress leaders who, they say, are accused of corruption. Are they facing any case in the country,” asked Sharma who is also the Deputy Leader of Opposition in the Rajya Sabha. “They must tell the source of the thousands of crore that they have used to contest in elections,” said Sharma. Sharma also accused the government of nurturing an environment in the country that has benefited the lumpen elements.
