This further entrenched white minority rule and made the country a republic, following a referendum result in favour in 1969. Under this new constitution, there was a bicameral Parliament consisting of an indirectly elected Senate of Rhodesia, and a directly elected House of Assembly of Rhodesia, in which the majority of seats were reserved for whites even more effectively than was the case under the Constitution of 1961. The new office of President was a ceremonial post, with executive power remaining with the Prime Minister.
