The Bishwa Bangla brand and the logo were created by Chief Minister Mamata Banerjee and she has given them to the state government on her own, Bhattacharya told reporters.
His statement came in the wake of newly-inducted BJP leader Mukul Roy's claim that Bishwa Bangla is not a government entity but a private company owned by Abhiskeh Banerjee, nephew of Mamata Banerjee.
"This (Roy's claim) is absolutely wrong and baseless. It does not belong to anybody and nobody holds any copyright over it," Bhattacharya said.
