The federal member for Page says Kevin Rudd is the man to lead Labor to victory over Tony Abbott.
Janelle Saffin says the former prime minister did the right thing by resigning from his post as foreign minister.
The move has sparked intense speculation that there will be a vote on the Labor leadership early next week.
Ms Saffin says if that’s the case, she’ll be supporting Mr Rudd.
“Prime Minister Julia Gillard might call for a leadership challenge and if she does that and if Kevin Rudd runs, I would support him,” she said.
“He’s the best person to lead us and to lead us to defeat Tony Abbott.
“The best thing that can happen is yes, something come to a head, that’s clear, and (for) some of the reforms that need to happen within the party.
“We just have to stay focussed on what we do.
“What I’m worried about is doing the right thing.
“What happened in 2010 wasn’t right and I’ve said that, so I can only do what I believe is right.”
