A series of compromises led to the establishment of a cabinet system of government in 1967, with Ratu Kamisese Mara as the first Chief Minister. Ongoing negotiations between Mara and Sidiq Koya, who had taken over the leadership of the mainly Indo-Fijian National Federation Party on Patel's death in 1969, led to a second constitutional conference in London, in April 1970, at which Fiji's Legislative Council agreed on a compromise electoral formula and a timetable for independence as a fully sovereign and independent nation within the Commonwealth. The Legislative Council would be replaced with a bicameral Parliament, with a Senate dominated by Fijian chiefs and a popularly elected House of Representatives. In the 52-member House, Native Fijians and Indo-Fijians would each be allocated 22 seats, of which 12 would represent ''Communal constituencies'' comprising voters registered on strictly ethnic roles, and another 10 representing ''National constituencies'' to which members were allocated by ethnicity but elected by universal suffrage. A further 8 seats were reserved for "General electors" – Europeans, Chinese, Banaban Islanders, and other minorities; 3 of these were "communal" and 5 "national". With this compromise, it was agreed that Fiji would became independent.
