The betting odds suggest the spill motion will be defeated, but if there is a leadership ballot, Malcolm Turnbull is the hot favourite to be Australia’s next Prime Minister.

Bookie Sportingbet.com.au has odds of $1.80 that the spill motion will be defeated, versus $1.90 that it is successful.

However, should there be a leadership ballot this week, Mr Turnbull is the clear-cut $1.36 favourite at Sportingbet to win. Julie Bishop is a $3.75 second favourite to win the ballot, ahead of Tony Abbott at $6.50.
