It also asked him to the clear the air instead of hiding behind technicalities.
"Instead of answering our two straight questions, Chidambaram is diverting the subject to an unrelated topic of right-wing terror. Nation does not want to hear his sermons on left or right terror but on his role in the daylight robbery in 2G spectrum," BJP spokesperson Prakash Javadekar said.
The BJP maintained that Chidambaram, who was Finance Minister when 2G spectrum was alloted, is offering a "bizarre explanation" on FDI in Unitech and SWAN.
"The issue is not just technical whether the participation of telecom companies is a sale of shares or divestment. The issue is whether the owners share has got diluted or not?" Javadekar asked.
He added that it is also pertinent whether these "so called fresh shares" would have fetched the price, which they have fetched without Unitech and SWAN having 2G licenses.
"Chidambaram knows very well that substance of transaction is more important than the form of transaction," Javadekar said.
He claimed that Chidambaram had also evaded the second question asked by the BJP.
"Why did he suddenly change his stand from auction and agreed with A Raja`s price formula in July, 2008? Mr.
Chidambram, you owe a straight answer to our straight questions," Javadekar said.
