He also said that the Govt ordered inquiry as soon as the scam came to light and the goverment will go to the root of the issue.
"As defence minister I feel ashamed of this scandal," he said.
The defence minister also said that he did not believe a denial from Finmeccanica unit AgustaWestland that it paid any bribes to swing a $750 million chopper deal.
Antony said the company had responded to a show cause notice demanding an explanation of accusations by Italian prosecutors that millions of euros in kickbacks were paid before the deal was clinched.
"They have replied. They have denied the whole thing. We don't believe it," Antony said during a parliamentary debate.
