Asserting that Singh has an impeccable track record in the government and there has never been a question with regard to his integrity, he hit out at attempts "to politicise things in the ongoing investigations".
"If at all, this is being speculated, I would request keep this in mind that this should be a principle which should apply across the board," Tewari told reporters when asked at a function here about Union Minister Kamal Nath's remark that the PM will make himself available to CBI in the Coalgate investigation if a formal request is made.
At the outset, he said that the PM has extensively spoken inside and outside Parliament with regard to the government's transparency on the entire issue of coal block allocation.
"The PM has impeccable track record in the government. There has never ever been a question with regard to the integrity of the PM. It is most unfortunate an attempt has been made to politicise things in the ongoing investigations," he said.
