Malcolm Turnbull has ousted Tony Abbott as federal Liberal leader, winning a party room ballot 54-44.

Julie Bishop defeated Kevin Andrews for the deputy leadership 70-30, after Michael Ronaldson joined the meeting to take the total voter numbers to 100.

Mr Turnbull will become Australia's 29th prime minister once he is sworn in by the governor-general, most likely on Tuesday.
