Political activist Amiya Nath Bose was from a family of radicals. He was the son of Sarat Chandra Bose who was interned in India in 1941 for Forward Bloc activities, and the nephew of the better known Subhas Chandra Bose, founder and leader of the Forward Bloc movement and notorious for his allegiance to the Axis powers during the Second World War. It is perhaps no surprise then that Amiya Nath Bose was already involved in student politics in India, before his departure for Britain.

Bose went to England to attend university in 1937. He studied economics at the University of Cambridge, gaining a Second Class, and was called to the Bar in 1941, living between London and Oxford. According to Indian Political Intelligence documentation, he was strongly influenced by his uncle who recommended reading for him, attempted to secure for him correspondentships on Indian newspapers, and put him in touch with Pulin Behari Seal with whom he began a close working relationship. Soon after his arrival in Britain, he made trips to Germany and Austria, which the government considered to be suspicious behaviour. Further, rumours circulated about his dislike of the English, and fellow students of the Oxford Majlis claimed he was opposed to the politics of both Nehru and Gandhi, perhaps considering them to be insufficiently radical in their approach to British imperialism. On the arrest of his father in India for associating with the Japanese, Bose became increasingly embittered and his views increasingly in line with those of his uncle. In the early 1940s, surveillance reports claim that Amiya Nath Bose was circulating his uncle’s ‘Manifesto’ and listening to his speeches on a radio purchased specifically for this purpose, and that he had a large photo of him in his room.

Amiya Nath Bose, with his close associate Seal, was key to the formation of the Committee of Indian Congressmen in 1942, assuming the position of General Secretary. Also closely involved with the organization were the Birmingham-based doctor Diwan Singh and Said Amir Shah. Bose's and Seal's alleged pro-Axis leanings, however, caused tensions within this organization, eventually causing the departure from it of numerous Indians, as well as strong opposition from without. In 1944 Bose moved to Birmingham, with Seal and his family, to escape the bombings. As a consequence the CIC became active in the Midlands and the north, recruiting from among the Indian workers based there. In August 1944, Bose, together with Drs Dutt and Vakil, organized the Indian Political Conference in Birmingham. Bose also established the Council for the International Recognition of Indian Independence in the USA as a sub-group of the CIC in order to spread his political message internationally.

Bose left for India on 2 November 1944, citing family reasons and the desire to obtain recognition for the CIC from the Indian National Congress, and delegating his responsibilities in Britain to Pulin Behari Seal and Said Amir Shah. Once in India, he was appointed special correspondent for Cavalcade.
