His Majesty's Government desire to hand over their responsibility to authorities established by a Constitution approved by all parties in India in accordance with the Cabinet Mission's plan, but unfortunately there is at present no clear prospect that such a Constitution and such authorities will emerge. The present state of uncertainty is fraught with danger and cannot be indefinitely prolonged. His Majesty's Government wish to make it clear that it is their definite intention to take the necessary steps to effect the transference of power into responsible Indian hands by a date not later than June 1948…if it should appear that such a Constitution will not have been worked out by a fully representative Assembly before the time mentioned, His Majesty's Government will have to consider to whom the powers of the Central Government in British India should be handed over, on the due date, whether as a whole to some form of Central Government for British India or in some areas to the existing Provincial Governments, or in such other way seem most reasonable and in the best interests of the Indian people.
In regard to the Indian States, as was explicitly stated by the Cabinet Mission, His Majesty's Government do not intend to hand over their powers and obligation under paramountcy to any government of British India. It is not intended to bring paramountcy, as a system, to a conclusion earlier than the date of the final transfer of power, but it is contemplated that for the intervening period the relations of the Crown with individual States may be adjusted by agreement.
Mountbatten's relations with the Congress party had a flying start. The foundation of Nehru's friendship with Lord and Lady Mountbatten had been laid in March 1946 when the Indian leader visited Singapore. The political conditions in India too had changed in favor of the Congress. In post-independence India the Congress party was expected to rule the country. Consequently, it was the Congress's friendship that had now to be cultivated. The fact that Mountbatten personally was bitterly opposed to partition, made it much easier for him to court the Congress leaders.
All these factors greatly increased the already formidable odds facing the Quaid-i-Azam in his fight for Pakistan. In his meetings with Mountbatten, he refused to budge from the position that Pakistan was the only solution acceptable to the Muslim League.
