Simla Conference was an outcome of the British intention to appease the Indian political parties so that India pledges her support for England in the Second World War. The impact of Simla Conference was rather contrary. Lord Wavell who succeeded Lord Linlithgow suggested the Simla Conference in which he proposed the setting up of a new executive council with all Indian members. It further suggested that the working of the new executive council would be based on the Government of Act, 1935. In spite of its positive efforts it failed to convince any of the parties as this conference was condemned to be racially discriminating and creating a difference between the Hindus and Muslims over representation. Though nothing constructive came up with this Simla Conference yet it left some impact on the Indian politics.

The impact of Simla Conference was visible in two reactions. Firstly, from this point onward the communal question dominated the struggle for freedom. Indeed, the attainment of freedom was already certain. The conflict began between those who struggled to achieve a united and secular Indian state and those whose rigid sectarianism stood in the way of this accomplishment.

The whole exercise behind the Simla Conference highlighted the fact that getting independence from a reluctant authoritative government was no more a problem but a larger problem was to come to a common solution by both the parties who utilized all their popularity in quarrelling with each other .It was the most crucial time in Indian politics which was to be used in constructing an effective constitution for future.

The conference failed at the end of all efforts. At the end it only benefited the Muslim League who was successful in humiliating the British Government who had initially proposed the agenda for the conference. At the same time it humiliated the Indian National congress as well by forcing it to accept Muslim League on the same parity. The League was also successful in getting rid of the Unionist party which was the only existing Muslim opposition to the Muslim League.

Thus, the Simla Conference was important for Indian politics till the end of the Second World War. With the end of the war the importance of Simla Conference was reduced though Lord Wavell came back with a new proposal known as Wavell's new proposal in the month of September.
