Eveyone blames Mamta and TMC. Being a politician it is her 'JOB' to halt progress of the country by any means. I woudn't blame the TMC or ILLITERATE WB citizens for the agitation.
But TATA has no excuse for choosing WB for NANO. He would have been selling NANO and making tons of money had he chosen TN, AP, Ktka, MH, Kerala of Gujrat!!
