After whites endorsed the Internal Settlement by 85% in a referendum on 30 January 1979, Smith dissolved the Rhodesian parliament for the last time on 28 February. The RF won all the white seats in the April 1979 elections while Muzorewa and the UANC won a majority in the common roll seats with 67% of the popular vote; the PF rejected this, however, as did the UN, which passed a resolution branding it a "sham". Sithole, astounded that his party had won only 12 seats to the UANC's 51, suddenly turned against the settlement and alleged that the polls had been stage-managed in Muzorewa's favour. Mugabe dismissed the bishop as a "neocolonial puppet" and pledged to continue ZANLA's campaign "to the last man"; Nkomo similarly committed ZIPRA. On 1 June 1979, the day of the country's official reconstitution as Zimbabwe Rhodesia, Muzorewa replaced Smith as Prime Minister, at the head of a UANC–RF coalition Cabinet made up of 12 blacks and five whites. Smith was included as Minister without portfolio; Nkomo promptly dubbed him the "Minister with all the portfolios".
