in 1946. Jinnah decided to agree to the plan. The British still invited the Congress to form a government with the Muslim League and the Viceroy of India assigned the Office of Prime minister to Nehru of the Indian National Congress. World War II On 3 September 1939, British Prime Minister Neville Chamberlain declared the commencement of war with Germany. Shortly thereafter, Viceroy Lord Linlithgow followed suit and announced that India too was at war with Germany. In 1939, the Congress leaders resigned from all British India government positions to which they had elected. The Muslim League celebrated the end of the Congress-led British Indian government, with Jinnah famously declaring it "a day of deliverance and thanksgiving". In a secret memorandum to the British Prime Minister, the Muslim League agreed to support the United Kingdom's war efforts—provided that the British recognise it as the only organisation that spoke for Indian Muslims. Following the Congress's effective protest against the United Kingdom unilaterally involving India in the war without consulting with them, the Muslim League went on to support the British war efforts, which allowed them to actively propagandise against the Congress with the argument of "Islam in Danger". The Indian Congress and Muslim League responded differently over the World War II issue. The Indian Congress refused to support the British unless the whole Indian subcontinent was granted independence.

When World War II ended, the Muslim League's push for the Pakistan Movement and Gandhi's efforts for Indian independence intensified the pressure on Prime Minister Churchill. Given the
