A South Australian One Nation candidate has been dumped on the eve of the election after it was revealed he is reportedly wanted in the UK for allegedly failing to appear in court over sexual touching charges.

Aoi Baxter, who was running for the seat of Adelaide, is reportedly wanted in the UK court after allegedly failing to answer to charges of sexually touching a woman without consent.

Baxter was disendorsed from the One Nation party after the news came to light and his face was removed from pre-voting booths in a late hit for the party, which is polling as the state's second most popular.

Baxter was reluctant to speak this afternoon, but offered a short statement.

"So the one thing I will say is I believe in innocent until proven guilty," Baxter told 9News.

"That's all I'm going to say at the moment, I will be putting out a full statement though."

The party is yet to comment on the allegations.

Earlier, One Nation South Australia leader Cory Bernardi said success at the election would be having any candidates win a place in parliament.

"I can guarantee you if we have one voice, two or 10, we will have the strongest voice for all South Australians."

Despite One Nation's confidence, rivals are not convinced.

"I couldn't name you a single positive policy that One Nation are talking about implementing," Liberal leader Ashton Hurn said.

Premier Peter Malinauskas said One Nation was a party based out of Queensland that had "zero plans for South Australia".

Today, the premier was focused on major infrastructure as he toured a concrete facility in a nod to Labor's commitment to the Torrens to Darlington Project.

"My only hope is that I can wake up on Sunday morning and just get back to work," Malinauskas said.
