The elections for the federal council Chair come at a time when Maimane is under severe pressure to resign following the party's poor performance at the polls in May.
Zille told City Press yesterday that some of the DA's disillusioned leaders approached her after the elections with the idea of forming a new political party, but she turned them down. Speaking to Sowetan yesterday, Zille denied that if she were to be elected, it would mean Maimane's days are numbered.
"If I win I will stick to the job description [it is a support function] and I will behave professionally at all times with all concerned. It is not my job to comment on or select leaders for the party. This must happen at a congress."
Zille was also unhappy that her return was seen as a fight-back by the DA's old-guard.
"As far as the 'white liberal old guard' is concerned, it is a pity that people are resorting to the race card. That is contrary to the DA's political philosophy," she said.
Yesterday, the Sunday Times reported that a panel reviewing the DA's performance at the recent polls suggested that Maimane resign before the end of his term to allow for the party's renewal.
The panel was Maimane's own brainchild after the party lost voters to the Freedom Front Plus in May. He initially wanted it to include outside experts but the party decided on a panel made up of former leader Tony Leon, ex-DA policy guru Ryan Coetzee and Capitec Bank co-founder Michiel le Roux.
The panel is expected to hand over its report to the party's federal council later this month. But according to the newspaper, one of its major suggestions is that Maimane resign and a new leadership be elected. It also calls for a change of leadership in DA-led metros of Tshwane and Johannesburg and Cape Town.
It is not clear how this report will be received but senior DA leaders remain adamant that Maimane will stay at least until the next elective congress in 2021.
Senior DA leaders who spoke to Sowetan said they stood by Maimane.
"We don't fightback, we continue with the journey that we have started. There's nothing to fightback on. We believe in the journey that we have started.
"For the people that I speak to, we don't believe that the DA [under Maimane] has gone off-rail, so you cannot then put it like people want to come in there to stabilise.
"The DA is able, there is nothing to stabilise," said a senior DA leader.
KZN provincial leader Zwakele Mncgwango said that although they have not seen the report, there was general consensus between provincial leaders that Maimane is not going anywhere.
"All I can say is that federal leader [Maimane] must stay in the position until the next elective congress. We as provincial leaders [are] united on this matter," said Mncwango.
