With Assam Assembly polls due in three months the main opposition - the Congress - has announced an alliance with three Left parties and, significantly, the Badruddin Ajmal-led AIUDF (All India United Democratic Front). The announcement puts to rest speculation the party would distance itself from the AIUDF after many within voiced strong objections. A regional party - the Anchalik Gana Morcha - will also be part of the opposition alliance, it was revealed Tuesday night.
