Since John Howard was Australia's Prime Minister which ended in 2007, no one has served a full term in our top office. Kevin Rudd, Julia Gillard, Mr Rudd again, Tony Abbott, Malcolm Turnbull and today we will find out who is Prime Minister number 30.
Malcolm Turnbull has all but conceded that the Party no longer supports him and if that is the case he won't renominate in a spill and will quit politics altogether.
Three senior Government members have indicated they will run: Peter Dutton, Scott Morrison and Julie Bishop – but who are they?
Peter Dutton
The hardline conservative, Peter Dutton was Australia's first Home Affairs Minister after serving as the Immigration Minister. Mr Dutton appeals to the Right which feels as though its voice has been silenced.
