The 1961 elections were a bitter contest between the PPP, the PNC, and the United Force (UF), a conservative party representing big business, the Roman Catholic Church, and Amerindian, Chinese, and Portuguese voters. These elections were held under yet another new constitution that marked a return to the degree of self-government that existed briefly in 1953. It introduced a bicameral system boasting a wholly elected thirty-five-member Legislative Assembly and a thirteen-member Senate to be appointed by the governor. The post of prime minister was created and was to be filled by the majority party in the Legislative Assembly. With the strong support of the Indo-Guyanese population, the PPP again won by a substantial margin, gaining twenty seats in the Legislative Assembly, compared to eleven seats for the PNC and four for the UF. Jagan was named prime minister.
