Documents shared by the Ministry of External Affairs (MEA) with BJP state president K. Annamalai recently under the Right to Information Act, have no doubt established that then Tamil Nadu Chief Minister and DMK leader M. Karunanidhi was taken into confidence by the Centre before India signed an agreement with Ceylon (now Sri Lanka) on the Katchatheevu islet in 1974.

While this has exposed the claim of Karunanidhi who had said he was not a party to the cessation of Katchatheevu during his lifetime, the documents also throw light on how the Government of India cited the country’s security interests and a weak legal case against Sri Lanka to convince him of the proposal to cede the island.
