Bose is almost totally unheard of in Britain where everyone is convinced that Indian independence was the work of Gandhi who is almost worshipped as a saint. This interpretation is much more flattering to our national ego. Clement Attlee however assessed Gandhi's role as "minimal". It is not the case in India where " Netaji" has his portrait in parliament and both a main thoroughfare in Calcutta and Calcutta airport bear his name.
Bose's army contributed little to the Axis military effort but when it's members were put on trial after the war the reactions, including a mutiny of the Navy, convinced the British that they could no longer count on the loyalty of the Indian armed forces. Of course, this was not the only reason for the departure from India. The parlous state of the economy, American pressure and increasing opposition to imperialism at home were all factors.

The link above is to a programme on BBC Radio 4 in the series Things we Forgot to Remember with the former Cabinet Minister Michael Portillo. The series as a whole will be of interest to revisionists. It includes episodes on the Morgenthau Plan, (of course it does not mention the ethnic loyalty of Morgenthau or Harry Dexter White) the Bengal famine and Jesse Owens.
