Senior lawyer Ram Jethmalani on Tuesday said he will waive off legal fees from Delhi Chief Minister Arvind Kejriwal if he can't pay to fight a defamation case filed by Finance Minister Arun Jaitley.Jethmalani spoke to the media after Kejriwal reportedly wrote to the Delhi government to foot a Rs 3.4 crore bill from Jethmalani."I charge only the rich but for the poor I work for free. If the (Delhi) government doesn't pay or he (Kejriwal) can't pay, I will appear for free. (I) will treat him as one of my poor clients," Jethmalani said.He accused Jaitley of instigating all this because the minister was "afraid of my cross-examination".
