The December 1964 elections for the new legislature gave the PPP 45.8% (24 seats), the People's National Congress (PNC) 40.5% (22 seats) and the United Force (UF) 12.4% (7 seats). The UF agreed to form a coalition government with the PNC, and accordingly, the PNC leader became the new Prime Minister. In November 1965 an independence conference in London quickly reached agreement on an independent constitution; it set the date for independence as 26 May 1966. On that date, at 12 midnight, British Guiana became the new nation of Guyana.
