Mr Ashby said Senator Hanson would want to be replaced by a “strong character”, and “she would be grateful if [her] legacy was led by people like Peter Georgiou, Mark Latham, Steve Dickson, Malcolm Roberts. If that is her legacy, she would be very proud." Senator Georgiou is the only remaining One Nation senator apart from Senator Hanson. Mr Roberts is a former One Nation senator and Mr Dickson leads the party in Queensland. Mr Latham has re-ignited speculation about whether he will re-enter politics, following his intervention in the crucial Longman by-election, due to be held as one of five “Super Saturday” federal by-elections on July 28. Although Mr Latham is currently a member of Senator David Leyonhjelm’s Liberal Democratic Party, he recorded robocalls for both the LDP and the One Nation campaign in Longman. Onetime guru to Pauline Hanson and One Nation co-founder, David Oldfield, says Mr Latham would be an ideal Senate candidate in New South Wales for the party, broadening its appeal to “old Labor” as well as conservatives.

“I’m quite supportive of Latham” Mr Oldfield told Fairfax Media. “If Latham was to take over One Nation it would be the best thing for One Nation and One Nation supporters, without question. The idea would be that Pauline would take a bit of a back seat and be the party figurehead, she could be the empress and he could be the person who takes the fight forward.” Mr Oldfield, who has fallen out with Ms Hanson, said she had little capacity for the cut and thrust of parliament and was mainly interested in adulation. “Latham is smart, and has the capacity to make and argument... Latham is a person who could potentially very much grow One Nation, whereas One Nation can’t do much more than it is currently doing under Pauline" Mr Oldfield said. Mr Latham’s re-entry to politics would be easier if he stood for the New South Wales upper house, where around 4 per cent of the vote would be enough to get him elected.
