"Bengal respects all languages and languages of all states. Our three language formula shows how we really do," the chief minister said.
"India is a vast country and the strength of our nation is unity in diversity. We must respect every mother tongue and also give every regional language its importance. We believe in the freedom of choice and the three language formula," Banerjee said.
"Students have the freedom to take any language of their choice as a first language, second or third language but one of the three languages would have to be Bengali," Banerjee said.
"If the student chooses Bengali, Hindi, English, Urdu , Gurmukhi, Nepali, Alchiki as a first language, he/she may opt for two other languages of their choice. One of the three languages would have to be Bengali," she said.
