Trinamool Congress chief Mamata Banerjee is game to talk to the Tatas if they want to speak to her on setting up the Nano plant in Singur, but said the auto major will have to return 400 acres of land acquired from farmers for the project.

"If the Tatas want to speak to us on Nano, I will talk. But they have to build the factory on 600 acres after returning 400 acres," Banerjee said in an interactive programme on Bengali television channel Star Ananda Monday night.
