Australia will get its fifth prime minister in eight years after the ruling Liberal Party on Monday voted out Tony Abbott in favor of longtime rival Malcolm Turnbull, following months of speculation and crumbling support from voters.

Turnbull, a multimillionaire former banker and tech entrepreneur, won a secret party room vote by 54 to 44, Liberal Party whip Scott Buchholz told reporters after the meeting in Canberra.

Foreign Minister Julie Bishop was elected deputy leader of the party that, with junior coalition partner the National Party, won a landslide election in 2013. The popularity of the government and Abbott in particular has suffered from a series of perceived policy missteps, destabilizing infighting and leaks.
