Tamil Nadu Chief Minister M Karunanidhi said on Friday that sustained efforts would be taken after the June 2010 International Classical Tamil conference to make Tamil an official language of the Union Government.

“Efforts for the benefit of Tamil language would not just stop with the classical Tamil conference in Coimbatore but we will make sustained efforts to ensure that it is made an official language of the Government of India,” Mr. Karunanidhi, whose DMK is a key constituent of the UPA, said.

Speaking to reporters here after chairing a review meeting of scholars and officials on the progress of works for next year’s conference, he said “we will keep doing it until we succeed.”

Urging all parties in the state to participate in the conference setting aside mutual differences, he said the focus should be on the development of Tamil.

Invitations had been extended to President Pratibha Patil, Prime Minister Manmohan Singh and UPA Chairperson Sonia Gandhi to participate in the event, he said.

More than 1200 delegates from many countries including US, UK, Singapore and Sri Lanka were expected to participate in the conference, Mr. Karunanidhi said.
