The Enforcement Directorate(ED) began interrogating former Finance Minister P Chidambaram on Friday in the INX media money laundering case.
The quizzing comes after his son Karti was grilled on Thursday. Chidambaram is the first accused in the case. Chidambaram has stuck to the stand that all accusations against him were unfounded and levelled as part of political vendetta.
The ED has already got the approval of the Central Government to prosecute both Chidambaram and his son.
