A big war of words has broken out between the BJP and the Congress over P Chidambaram's arrest in the INX media case. While the Congress claimed that the arrest was mere vendetta, the BJP said the law is taking its own course. Meanwhile, Chidambaram's son Karti said that he had never met Indrani Mukerjea before he was confronted with her by the CBI. He also added the Congress will fight the case legally and politically.
