Union finance minister Arun Jaitley on Monday filed another defamation case of Rs 10 crore against Arvind Kejriwal over use of an "objectionable" word by Delhi CM's lawyer Ram Jethmalani in the Delhi High court. Jaitley, who holds the twin portfolios of finance and defence, filed the fresh suit after Kejriwal's counsel Ram Jethmalani allegedly abused him in open court during the proceedings of another defamation suit he had filed against the Aam Aadmi Party (AAP) chief and five other party leaders.
