In
1965, the year of
Rhodesia's Unilateral Declaration of Independence, Smith was elected to the
Southern Rhodesian Legislative Assembly for the
Marandellas constituency. On 28 September 1968, he was named to Prime Minister
Ian Smith's cabinet as
Minister of Agriculture, succeeding
George Rudland. At that time, Smith was described as the
Rhodesian Front's "most liberal MP" and a
moderate within the party who opposed press
censorship and favoured a settlement with Britain. He was reelected to Parliament in the
1970 election with 72.5 percent of the vote against
independent candidate Thomas Edridge, a
Wedza farmer and member of the
Rhodesia Tobacco Association's governing council. Edridge and the RTA took issue with
price controls put in place by Smith in his capacity as agriculture minister. Smith was reelected in
1974 with 79 percent of the vote against Alfred John Harrison, the
Rhodesia Party candidate. on 3 March 1978. On 13 January 1976, Smith was made
Minister of Finance after the incumbent minister,
John Wrathall, became
President of Rhodesia. That year, he was the first Rhodesian minister to say he would run for Parliament under the Internal Settlement constitution, which would ensure a multiracial government. In a
by-election held on
24 July 1979 to replace
Hilary Squires, Smith was elected unopposed to Parliament for the
Borrowdale constituency. In the fall of 1979, he attended the
Lancaster House Conference as part of Zimbabwe Rhodesia premier
Abel Muzorewa's delegation. After the conference, which ended the
Rhodesian Bush War and led to the creation of the independent
Zimbabwe, he kept in personal touch with nationalist leaders
Robert Mugabe and
Joshua Nkomo. He was one of two whites in the cabinet, along with agriculture minister
Denis Norman, and was the only minister belonging to the Rhodesian Front. He said he would remain in the party, and Ian Smith played a role in his selection for the cabinet. Later that year, his title was changed to Minister of Trade and Commerce, with the industry portfolio going to
Simba Makoni. In early March 1981, Smith resigned from the cabinet, citing ill health. He resigned from Parliament and the Rhodesian Front on 30 April, saying in a statement that he had decided to retire from politics but would be "an interested onlooker". == Later life and death ==
