Khwaja Nazimuddin was selected as governor general after Jinnah's death. But the actual responsibility for running the government and leading the nation was taken by Prime Minister Llaqat Ali Khan. Constitutionally he was already the leader of a parliamentary cabinet, but in the lifetime of Jinnah the cabinet was practically a presidential one in which Liaqat was the most senior minister and the person in whom Jinnah had the most confidence. This resulted from the unique position held by Jinnah in the national life of Pakistan; it was not part of the constitution.
