It was around this time that the demand for an independent Pakistan was first made.
From Wikipedia: On 3 September 1939, British Prime Minister Neville Chamberlain announced the commencement of war with Nazi Germany. The following day, the Viceroy, Lord Linlithgow, without consulting Indian political leaders, announced that India had entered the war along with Britain. There were widespread protests in India. After meeting with Jinnah and with Gandhi, Linlithgow announced that negotiations on self-government were suspended for the duration of the war. The Congress on 14 September demanded immediate independence with a constituent assembly to decide a constitution; when this was refused, its eight provincial governments resigned on 10 November and governors in those provinces thereafter ruled by decree for the remainder of the war. Jinnah, on the other hand, was more willing to accommodate the British, and they in turn increasingly recognised him and the League as the representatives of India’s Muslims. Jinnah later stated, “after the war began, … I was treated on the same basis as Mr. Gandhi. I was wonderstruck why I was promoted and given a place side by side with Mr. Gandhi.” Although the League did not actively support the British war effort, neither did they try to obstruct it.
With the British and Muslims to some extent cooperating, the Viceroy asked Jinnah for an expression of the Muslim League’s position on self-government, confident that it would differ greatly from that of the Congress. To come up with such a position, the League’s Working Committee met for four days in February 1940 to set out terms of reference to a constitutional sub-committee. The Working Committee asked that the sub-committee return with a proposal that would result in “independent dominions in direct relationship with Great Britain” where Muslims were dominant. On 6 February, Jinnah informed the Viceroy that the Muslim League would be demanding partition instead of the federation contemplated in the 1935 Act.
