A double referendum was held in Rhodesia on 20 June 1969, in which voters were asked whether they were in favour of or against a) the adoption of a republican form of government and b) the proposals for a new Constitution, as set out in a White paper and published in a "Gazette" Extraordinary on 21 May 1969. Both proposals were approved. The country was subsequently declared a republic on 2 March 1970.
