West Bengal chief minister Mamata Banerjee may be getting ready to bury the hatchet with Tata group chairman Ratan Tata. Banerjee is all set to appeal to Tata and other industry leaders to invest in West Bengal, following her victory in the recent elections and the defeat of the Communists, putting an end to their rule of 34 years in the state. The sales pitch will be made by Banerjee at an 18 June conclave in Kolkata that’s being billed as the biggest ever such meeting in the state.
