Top lawyer Ram Jethmalani has said that if Delhi Chief Minister Arvind Kejriwal cannot afford to pay his fee, he will not charge the politician to defend him in court. His offer comes after a controversy was triggered by Mr Kejriwal's government attempting to pay his Rs 3.8 crore bill using public funds for defending Arvind Kejriwal in a criminal defamation case filed by Finance Minister Arun Jaitley. The Delhi Chief Minister's petition in court refers to the case as a 'private' matter. Does the question of public interest arise at all?
