In 1971, following the retirement of sitting Country Party member Bill Weiley, Singleton was selected as one of two Country Party candidates for the state seat of Clarence. Although outpolled by the Labor Party on the primary vote, the preferences of the second Country candidate and two independents gave him a fairly comfortable victory with 55.11% of the two-party-preferred result.^[2] In 1981, Singleton's seat was made notionally Labor and he transferred to the new seat of Coffs Harbour.^[3] He served eleven months as Minister for Administrative Services and Assistant Minister for Transport in the Greiner government from 1988 to 1989, before resigning from politics in 1990.^[1]
