The opposition parties seem to be divided over the boycott of home minister P Chidambaram, over his alleged role in the 2G-scam. While the BJP is firm on not to allow the minister to speak in Parliament, the Communist Party of India-Marxist (CPM) has opposed Chidambaram's boycott. The National Democratic Alliance on Monday announced the boycott of Chidambaram in Parliament for his alleged role in allocation of telecom licences.
