Patna, Oct 31: The Lok Janshakti Party has called `rail chakka jam` agitation in Bihar to protest the Centre`s decision to close down the Barauni Fertiliser Plant of the Hindustan Fertiliser Corporation. Accusing the Centre of having hatched a conspiracy to wipe out Bihar from the country`s industrial map, Singh told a news agency that his party would not allow the Centre to close a prestigious asset of Bihar. He alleged that even the state government had failed to oppose the Centre`s sinister move. Singh urged Chief Minister Rabri Devi to convene a special session of the state legislature to oppose the decision for closure of the Barauni Fertiliser unit. Bureau Report
