India should support the UN inquiry into mass atrocities in Sri Lanka and ensure it succeeds urged a Tamil Nadu delegation of politicians and activists, in a meeting with the country's external affairs minister Sushma Swaraj on Wednesday, the Times of India reported.

The delegation, comprising the PMK youth wing leader, Anbumani Ramadoss, retired IAS officer Devasagayam, former MP for Dharmapuri, Senthil, and a representative from the Civil Society Coalition for Justice and Peace, K Balu, submitted a memorandum urging the BJP government to proactively support and assist the inquiry.

"Considering the fact that the Sri Lankan government has repeatedly betrayed its trust, misplaced though it may be, India should support the investigation and adopt a proactive role to facilitate the 'credible international investigation' to succeed", the memorandum reportedly said.

"People of India voted for a change and gave a historical verdict. We submit that the government stands up to that high expectation and puts its heart and mind for a change in India's policy towards Sri Lanka in every spear," it added.

Speaking after the meeting, Ramadass said the "NDA should change its policy towards Sri Lanka and should not follow the line of the previous UPA government", reported the PTI.

Calling on the Indian government to appoint an independent person, to act as a special representative regarding Sri Lanka - India relations, the delegation said, "this could enthuse the Tamils and lead to an early healing of the festering wound that could otherwise turn into gangrene."
