In a midnight tweet on the occasion of the 73rd Independence Day, Banerjee urged one and all to take an oath "not to divide India", but to unite it.

Saluting the nation "and all our countrymen and women", the Chief Minister said: "We must always strive for political freedom, economic freedom, freedom of expression, and preserve democratic rights. When these are not given, we should organise peaceful movements to preserve these rights."

In another tweet, she said democracy was India's most priceless asset.

"Let us take an oath today, not to divide India. We must unite India. Irrespective of caste or creed, we are all one India. Secularism is what identifies and unites us as a nation."
