The onus was now on Congress. It accepted the proposals, understanding it to be a repudiation of the demand for Pakistan, and its position was that the provinces should be allowed to stay out of groups that they did not want to join, in light of both NWFP and Assam being ruled by Congress governments. However, Jinnah differed and saw the grouping plan as mandatory. Another point of difference concerned the Congress position that a sovereign constituent assembly would not be bound to the plan. Jinnah insisted it be binding once the plan was accepted. The groupings plan maintained India's unity, but the organisation's leadership and, most of all Nehru, increasingly believed that the scheme would leave the centre without the strength to achieve the party's ambitions. Congress' socialist section led by Nehru desired a government able to industrialize the country and to eliminate poverty.
