West Bengal CM Mamata Banerjee posted on X, "Saddened by the demise of Ratan Tata...The former Chairman of Tata Group had been a foremost leader of Indian industries and a public-spirited philanthropist." Notably, Mamata's movement against land acquisition for a Tata Motors plant in Bengal's Singur to manufacture Nano had compelled Tata Group to move the project to Gujarat's Sanand.
