"In the case of Kapil Sibal, it is being said that he gave relief to an industrial house by heavily reducing the penalty to nominal. This should be seriously investigated as these are the companies which have been associated with the scams," senior BJP leader Murli Manohar Joshi told reporters in Varanasi.
Joshi, who as the PAC chairperson has looked into the 2G spectrum allocation scam, asked the government to clarify its position on the controversy surrounding Sibal.
A PIL in the Supreme Court has alleged that Sibal reduced a Rs 650 crore penalty on Anil Ambani-owned Reliance Communications, to Rs 5 crore.
"The government should reveal the truth behind the allegations against Sibal. And if this allegation is true, then a CBI inquiry should be ordered into the matter," Joshi said.
