The Tamil Nadu Legislative Assembly on Monday unanimously passed a resolution making the rendition of Tamil Thaai Vazhthu, the state's official song, mandatory at the beginning of government functions across the state.

The resolution was moved by Chief Minister C. Joseph Vijay, who said his government would not compromise on Tamil Nadu's linguistic and cultural identity. Addressing the Assembly, Vijay described Tamil as more than just a language, calling it the state's "life and emotions."

"Mother tongue is as pure as our mother," the Chief Minister said, adding that giving Tamil the foremost place was a matter of protecting the state's rights and cultural heritage.

The resolution received unanimous support from members across party lines, including the DMK and AIADMK, allowing it to pass without opposition.

Under the resolution, Tamil Thaai Vazhthu will be sung at the commencement of programmes held in government offices, educational institutions, universities, and public sector undertakings across Tamil Nadu.

The move comes amid a broader national discussion on official ceremonies, following a recent advisory from the Union Ministry of Home Affairs asking states and Union Territories to comply with its directive to play the National Song "Vande Mataram" before the National Anthem at official events.

The Tamil Nadu government has maintained that the resolution is aimed at strengthening the state's linguistic and cultural identity while preserving its traditions at official functions.
