Shiv Sena today slammed Congress for fielding former Union minister P Chidambaram from Maharashtra for the Rajya Sabha poll, saying the party has "damaged itself by foisting him on the state".

An editorial in Sena mouthpiece 'Saamana' noted that the ED has sent Letters Rogatory (judicial requests) to UK and Singapore in connection with its money laundering probe in the Aircel-Maxis deal case and parallel investigations in the financial transactions of some companies belonging to friends of former Finance Minister P Chidambaram's son Karti.
