NEW DELHI: Nalini Chidambaram , wife of former Union minister P Chidambaram, has been questioned by CBI in connection with the Saradha chit fund scam.

Chennai-based senior lawyer Nalini Chidambaram was dragged into the Saradha scam after Sudipta Sen, the disgraced chairman of the busted chit fund, claimed he paid more than Rs 1 crore to her at the instance of Manoranjana Singh, the estranged wife of Congress leader Matang Singh.In an 18-page letter to CBI, which police has confirmed as genuine, the Saradha boss alleged that he paid for Nalini Chidambaram's visits to Kolkata and for her stays in a 5-star hotel. He went on to add that Nalini pressured him to invest Rs 42 crore in Manoranjana's company without "assessing my financial strength".(With inputs from PTI)
