Clare Valley wine-maker Kathleen Bourne confirmed on Friday that she had withdrawn from the Liberal Party preselection race for the seat of Frome.
This leaves Port Pirie’s Kendall Jackson and Wandearah’s Brenton Vanstone as the remaining contenders for preselection.
The party will decide the successful representative at Balaklava on Saturday, February 25.
Both Mrs Jackson, a former ABC journalist, and Mr Vanstone, a former Port Pirie mayor, have sent letters to Liberals in the area outlining their claims on the position.
Ms Bourne was originally endorsed by former Clare-based Liberal senator Sean Edwards.
She unsuccessful tried to unseat Labor’s Nick Champion in the seat of Wakefield around Balaklava and Port Wakefield at the federal election last year.
The preselected Liberal candidate will challenge sitting Independent Member and Cabinet Minister Geoff Brock. Mr Brock told The Flinders News that he will recontest the seat.
