"This scam is defence related and Bofors scam was also defence related. In the Bofors scam the name of an Italian firm and some people had emerged. In the helicopter scam also the name of an Italian firm has come out," Joshi said.
Joshi also hinted that the BJP would not allow the budget session of parliament to function if the Congress did not give in to the opposition demand for an inquiry in totality and sat for discussions with it.
"If they want parliament to function they should discuss these issues with us and they should accept our demand," he said.
Joshi also accused the Congress of trying to divert attention from scams by blaming other parties.
"Whenever a corruption or scam comes out in open. They blame other parties. They just want to play the blame game and save their backs," he added.
