A political blame game has erupted in West Bengal over the compensation awarded to the Tata Group. Tata Motors Ltd. said an arbitration panel has ruled in its favour to recover Rs 766 crore with interest from the West Bengal Industrial Development Corporation in the Singur-Nano project case. The company had claimed compensation on account of the loss of capital investments made during the previous Left Front regime for the Tata Nano factory in Singur. Earlier the Supreme Court had ruled that the land acquisition for the project by the Left Front government led by Buddhadeb Bhattacharya was illegal.
