On Tuesday morning, Australia woke up to its fifth prime minister in just over five years. Multi-millionaire investment banker Malcolm Turnbull had defeated sitting PM Tony Abbott in a party-room challenge the previous evening, just under two years into Abbott’s first term of office.

The irony was lost on no one, as Abbott had led the center-right Liberal Party–National Party “Coalition” to a landslide victory in September 2013 in large part by pointing to the disarray of the previous six years of Labor Party rule, which saw not one but two successful coups against sitting PMs. Indeed, in his final public pitch to keep his job Abbott claimed, “We are not the Labor Party.”

Just hours later he had been deposed by a vote of his fellow members of parliament, fifty-four votes to forty-four. This was a remarkable reversal from 2009, when Abbott successfully challenged then–Opposition Leader Turnbull.
