New Delhi: Unfazed by Congress' warning to bring a privilege motion against BJP MP Subramanian Swamy for lying in Parliament during the AgustaWestland debate, the latter on Friday dared the Grand Old Party saying he will teach them law.

The veteran BJP leader had even attacked Congress in a series of tweets yesterday.

What Congi idiots do now? Christian Michel says to Barkha on NDTV his 2008 Note I produced in RS stating TDK was "driving force" is genuine! — Subramanian Swamy (@Swamy39) May 12, 2016

The reaction noted lawyer and firebrand BJP MP came hours after the Congress said that it would bring a privilege motion against him and his colleague and Defence Minister Manohar Parrikar in conncetion with the AugustaWestland case.

The announcement was made by senior Congress leader Jairam Ramesh who said, "These two leaders have been lying blatantly and brazenly."

"Subramanian Swamy spoke against Sonia Gandhi and other Congress leaders in Parliament and kept referring a document which according to him was an Italian court's judgement. In reality, this is a 13-page document consisting of two page of emails from Swamy to himself. Nine pages of the report were downloaded from www.pgurus.com and the remaining two pages are part of a news story run by an Indian news channel," Ramesh added.

The motion against Swamy is likely to be filed with Rajya Sabha chairman Mohammad Hamid Ansari on Friday, the last day of the ongoing session, Ramesh said.

"The document which Defence Minister Manohar Parrikar referred as the Italian court's judgment in the Lok Sabha are actually minutes of a meeting attended by the NSA," Ramesh said.

Meanwhile, AICC also announced that the party will file defamation case against a US-based website, www.pguru.com, whose material was used by Swamy in the Rajya Sabha debate. It alleged that the website is linked to the Sangh Parivar.
