Finance Minister Arun Jaitley, who has sued Arvind Kejriwal's Aam Aadmi Party (AAP) for defamation, was cross-examined in open court today by fellow lawyer Ram Jethmalani. In course of a back-and-forth that went on for hours, Mr Jaitley was asked to explain how he called the damage to his reputation "irreparable and unquantifiable" and whether it had anything to do with his "personal feelings of greatness". Mr Jethmalani, a former BJP leader, was unsparing as he demanded that Mr Jaitley explain - why the defamation suit.
