In a bid for investments, Chief Minister Mamata Banerjee is all set to take on Vibrant Gujarat with a Bengal Global Summit of her own. Vibrant Gujarat, launched by Narendra Modi in 2003 when he was Chief Minister, begins on Sunday, Mamata's tomorrow. Her chief guest: Arun Jaitley with whom she has recently crossed swords on the new Goods and Services Tax and the Land Ordinance, which makes it easier for industry and the government to acquire land from farmers. But her right-hand man, Amit Mitra, says government is government and politics, politics. What's more, Mr Mitra says Bengal is ready to compete with Vibrant Gujarat to win investments - foreign and domestic.
