Trinamool Congress is open to local alliances in Assam with parties that are aggressively fighting the BJP but "under no circumstance" will it ally with Badruddin Ajmal-led AIUDF, the saffron party's "B-team", said state unit chief Ripun Bora on Saturday. Observing that the TMC will support the opposition's joint candidate in the upcoming presidential election, Bora, however, remained non-committal on whether the Mamata Banerjee-led party will enter into any understanding with the Congress in Assam as the grand old party is "not fighting BJP in the way it should have".
