The Prime Minister who sent the Cripps Mission to India was Winston Churchill.

The Cripps Mission was dispatched to India in March 1942 during World War II. The mission was aimed at securing Indian support for the war effort and obtaining cooperation from the Indian National Congress, which was demanding independence from British rule.

Winston Churchill, serving as the Prime Minister of the United Kingdom at the time, authorized the Cripps Mission as a response to growing political unrest in India and the need to secure India`s support in the war against the Axis powers. The mission was led by Sir Stafford Cripps, a prominent British politician and member of the War Cabinet.

Sir Stafford Cripps presented a proposal known as the Cripps Offer, which included the promise of dominion status and the possibility of full independence for India after the war, provided that the Indian political parties could agree on a post-war framework. The proposal was, however, met with widespread dissatisfaction by Indian political leaders, as it did not grant immediate independence and was seen as inadequate.

The mission ultimately failed to achieve its objectives, and the deadlock between the British government and Indian political leaders persisted. The Cripps Mission is often viewed as a significant event in India`s struggle for independence, as it highlighted the growing demand for full independence and exposed the limitations of British attempts to retain control over India.

In summary, Winston Churchill, the Prime Minister of the United Kingdom, sent the Cripps Mission to India in 1942. The mission`s purpose was to secure Indian support for the war effort, but its proposals were not satisfactory to Indian political leaders, contributing to the growing demand for independence.
