In December 2018, Prime Minister Narendra Modi, who was on a two-day visit to the Andaman and Nicobar Islands, renamed three of the islands as a tribute to Netaji Subhash Chandra Bose. The Ross Island was renamed as Netaji Subhash Chandra Bose Dweep; the Neil Island as Shaheed Dweep; and the Havelock Island as Swaraj Dweep. The PM made this announcement during a speech at the Netaji Stadium, marking the 75th anniversary of the hoisting of the Indian flag by Bose there.
