NEW DELHI: The Centre has decided to rename three islands in Andaman & Nicobar - Ross Island as Netaji Subhas Chandra Bose Island, Neil Island as Shahid Dweep and Havelock Island as Swaraj Dweep - coinciding with the 75th anniversary of Bose having hoisted the national flag in Port Blair Sources said the home ministry has almost completed formalities for the change in nomenclature and the new names will be announced by Prime Minister Narendra Modi during his visit to Port Blair on December 30. Modi, who will be accompanied by home minister Rajnath Singh , will hoist a 150-metre flag in Port Blair apart from releasing a commemorative stamp and coin on the occasion.After the Japanese captured the islands during WWII, Bose, who led the Indian National Army that had allied with Japan, hoisted the national flag in Port Blair on December 30, 1943. He declared the islands as the first Indian territory freed from British rule. He then suggested Andaman be renamed as Shahid Dweep and Nicobar as Swaraj Dweep, something the Modi government is now taking forward by renaming Neil Island and Havelock Island .
