The Central Bureau of Investigation (CBI) on Friday summoned Nalini Chidambaram, the wife of former finance minister P. Chidambaram in the Saradha chit fund scam case. Nalini has to be present at CBI Kolkata office on March 10.

Earlier, the CBI had named Nalini, in the sixth supplementary chargesheet filed in the Saradha scam.

Nalini was named neither as witness nor accused, but as one privy to certain information on the controversial channel deal. The CBI said it might look into the information she was privy to “at a later stage”.

Nalini’s name first cropped up in the purported letter from Saradha boss Sudipta Sen to CBI in April 2013, where it was claimed that she had been paid from Saradha account.
