Since 1956, when India and Ceylon recognised the need for a maritime boundary, the ‘Kachcha Thivu [sic] Island Dispute’ echoed in the Lok Sabha, only to be overruled by PM Nehru
The island was ceded by the Indian administration under Prime Minister Indira Gandhi to Sri Lanka in 1974 in an act of bilateral largesse.
