There was chaos outside the BJP office in Kolkata after the party named its candidates for the Bengal elections. Those who didn't get a chance to contest the polls were angry that the BJP favoured several candidates, who had crossed over from the Trinamool Congress. Scenes like this at Jhargram, where he was to address a rally, brought Amit Shah back to Kolkata last night. The stopover was unscheduled; his meeting with BJP leaders in Bengal was long and angry, say sources.
