ED has summoned Nalini Chidambaram, wife of former Finance Minister P Chidamabram, in connection with its money laundering probe in the Saradha chit fund scam case.

Officials said Nalini has been asked to appear before the Investigating Officer of the case early next month in Kolkata where her statement is expected to be recorded under the provisions of the Prevention of Money Laundering Act (PMLA).

The particular matter with Nalini, a Supreme Court lawyer, pertains to the legal fee paid to her by the Saradha group, official sources said.

The amount in question is Rs 1.26 crore, sources said, and the Enforcement Directorate wants to understand the exact flow of funds to her from Saradha company accounts and the contract made therein. She had earlier been questioned by the ED and CBI in this regard but sources claimed she has been summoned on the "light of new evidence."
