Banerjee was sworn in as chief minister of West Bengal on 20 May 2011. As the first female chief minister of West Bengal, one of her first decisions was to return 400 acres of land to Singur farmers. "The cabinet has decided to return 400 acres to unwilling farmers in Singur," the chief minister said. "I have instructed the department to prepare the papers for this. If Tata-babu (Ratan Tata) wants, he can set up his factory on the remaining 600 acres, otherwise we will see how to go about it."
