Veteran South Australian MP Duncan McFetridge has confirmed he will run as an independent at the next state election after losing Liberal Party preselection for his southern Adelaide seat.
Dr McFetridge, who has held the seat of Morphett for 15 years, quit the party after the preselection and now says he will contest the seat at the state poll next March.
"I will be standing as an independent at the next election. I'm still there for the people of Morphett," he told ABC radio on Monday.
"The people of Morphett know I have been Liberal, always have been a Liberal.
"They know me, they trust me, they keep re-electing me with increased margins and that's why I want to continue."
Dr McFetridge said his intention was to support a Liberal government after next year's election but conceded the party had a poor record in dealing with independents, with a number supporting Labor in recent years.
He also revealed he had previously knocked back offers to jump ship and join the Labor government as a minister, a decision that had cost him a significant amount in extra pay.
Dr McFetridge, 65, has held Morphett since 2002, but recently lost preselection to former Collingwood footballer and local mayor Stephen Patterson.
The decision prompted him to quit the party as he "saw no point in remaining" and he has continued to sit on the cross benches.
The former veterinarian previously held a range of opposition front bench positions but was dumped by leader Steven Marshall in January.
He retained Morphett in 2014 with a margin of nearly 13 per cent but that was reduced to an estimated 7.7 per cent in last year's redistribution of electoral boundaries.
