She said to mediapersons in Kolkata, "We are considering legal action against him for his comments. He is speaking like a political leader. Let him contest an election from Bengal." On Friday, Oct 17 an open letter by Ratan Tata was published in all leading newspapers of West Bengal in which he warned people of 'destructive political environment of confrontation' that Tata said the Trinamool Congress was creating.
Criticising Mamata, Ratan Tata said, "The confrontative actions by the Trinamool Congress led by Mamata Banerjee and supported by vested interests and certain political parties have caused serious disruption to the progress of the Nano plant."
In response Mamata Banerjee said that Tata is taking political line of CPI-M while the people of the state is with her. "We are stunned by his comments. He owes a lot to the CPI-M. He got Rs 200 crore from the CPI-M to set up the plant here. On the other hand, he had to pay Rs 400 crore to the Gujarat government for the proposed factory at Sanand. So, he is giving certificates to the Bengal government," she said.
"It's a new form of joint venture – private brokership with Government money," she said sarcastically.
