Even after campaigning extensively in his home state of Tamil Nadu, Home Minister P Chidambaram’s electoral assignment for his party is not over. Soon he will fly to West Bengal to campaign for the Congress. He is likely to go to Kolkata on April 14 and address a press conference there. Efforts are on to make him address one or two rallies in the state capital too. The decision of the Congress assumes significance, as the home minister is not very popular in the Trinamool Congress, the partner of the Congress in Bengal. But the Congress decision makes it clear that it will pay no heed to its partner’s preferences.
