I can't remember where I heard it, but I remember hearing somewhere that the 1935 self-government act given to India by Britain would have sated the nationalists in 1919, while the self-government act they got then was too feeble; but in 1935 they wanted essentially independence. In OTL, of course, staunch pro-colonialist opposition in the UK kept the concessions one step behind what they would have needed to be. But let's assume Parliament magically draft and pass the GoI Act 1935 in place of the GoI Act 1919, with expanded local government powers, elected representation for Indians, etc. How does the world react? Does the INC accept this for the time being? Do they split into pro- and anti- factions? Is there a backlash and a movement for repeal among the British public?
