Former union minister P Chidambaram, with investigating agencies on his trail, failed to win a reprieve this morning after he asked the Supreme Court for an urgent hearing on his petition for anticipatory bail in the INX Media case. The Enforcement Directorate has put out a lookout circular for Mr Chidambaram, who has not been seen since the High Court denied him protection from arrest on Tuesday, after which the CBI visited his home in Delhi twice.
