West Bengal’s finance minister Amit Mitra doesn’t seem to too comfortable with his responsibilities, and sources say that he met Mamata Banerjee and clearly told her that she should look for his replacement. Actually, Mitra, who was once the apple of Mamata’s eyes, has had enough of Mamata’s populist policies, especially the no tax policy. Mitra, who is primarily an economist, can’t digest this strange marriage of economics and politics. Sources close to didi have revealed that she is set to give a major shock to Dinesh Trivedi before the forthcoming Railway Budget.
