The coming assembly elections in Bengal will be a fight between Prime Minister Narendra Modi's "development model" and Chief Minister Mamata Banerjee's "destruction model", Union minister Amit Shah said at a rally in north Bengal's Cooch Behar today. Bengal is the biggest prize the BJP is hoping to draw in the coming round of assembly elections. Mr Shah has set the state party a target of 200 of the state's 294 seats.
