Try this reality seed
Gandhi,
Jinnah, and
Nehru all get assassinated on the same day in the early 1930's. The assassin was about to kill the viceroy of India when
B. R. Ambedkar slugged him with a chair leg. Ambedkar becomes the hero both of the independence movement and the local Brits. Churchill hated Gandhi deeply (maybe because they were both a strange mix of visionary idealist and hidebound reactionary) but in this reality Ambedkar manages to deal pleasantly with Churchill.
India has self-rule from 1933 on, independence comes later (1950) but there is no partition of India and Burma/Myanmar remains part of India as well. Gandhi's anti-technological biases and anti-birth control ideas never have any influence. India on the same development track as the East Asian tigers from 1950 on, only with fewer setbacks and ecconomic stocks. India's government is famous for a lack of corruption and a high level of efficiency.
The downside is that the China India rivalry is much nastier and more bitter.
