New Delhi, Dec 19 (PTI): Hitting back at the Aam Aadmi Party after it launched a fresh attack on Finance Minister Arun Jaitley, the BJP has alleged that Delhi Chief Minister Arvind Kejriwal had become a "champion of lies" from a self-appointed champion against corruption and was "abusing" everybody to save his "corrupt" colleagues.

The BJP dismissed as "false and foolish" five questions posed to the Finance Minister by AAP leader Ashutosh and accused the party of using "diversionary tactic" to deflect attention from the corruption charges against Mr Kejriwal's principal secretary.

"Jaitley has been in public life for longer than the age of Kejriwal and his integrity has never been in question. Kejriwal and his party have been levelling such false and foolish charges just to save a corrupt officer," BJP media cell in-charge Shrikant Sharma said, wondering why the AAP was going to such lengths to save an officer.

Mr Kejriwal is "abusing" Prime Minister Narendra Modi, Mr Jaitley and is attacking the media, he said.

Mr Sharma alleged that Mr Kejriwal has always defended his colleagues found on the wrong side of law and recalled how he had protected former Delhi Law ministers Jitender Singh Tomar and Somnath Bharti, who have faced charges of forging certificate and domestic violence respectively and were arrested.

"Kejriwal was a self-appointed champion against corruption. In power, he has become a champion of lies," he said, adding that in his frustration, Mr Kejriwal was also targeting the media.

Calling Mr Jaitley a "master of half-truth and beautiful lies", AAP's Ashutosh had made certain fresh allegations against him and said his comment that there were no specific charges against him was "misleading".
