Australia has shown how quickly the right can crumble. Boris Johnson, be warned | Gaby Hinsliff

The ousting of shameless culture warrior Scott Morrison, and his defeat in wealthy heartlands, should send a shiver down Tory spines

Populists can be beaten. There was a time not long ago when few could type that sentence with confidence, so the outcome of Australia's recent elections will leave many progressives battling with the still unfamiliar sensation of victory.

Scott Morrison, the now ousted rightwing prime minister dubbed Australia's first post-truth" leader, was never quite a Trumpian. But he was a shameless culture warrior presiding over a bungled Covid response and ensuing recession, plus a clumsy response to high-profile sexual misconduct allegations against parliamentary colleagues. He dragged his feet on the climate crisis even as apocalyptic floods, fires and droughts were convincing Australians that something had to change, and holidayed in Hawaii as wildfires raged at home. His opponent, Labor's Anthony Albanese, was not exactly overburdened with charisma and the progressive vote eventually split between Labor, the Greens and the so-called teal independents, an exasperated army of mainly female candidates pledging to clean up politics and tackle the climate. But the cautious Albanese and his mantra of safe change" - nothing too big or scarily radical - still made it over the line, having seemingly learned from a previous Labor defeat blamed on an over-ambitious manifesto. If any of this sounds uncannily familiar to British readers, then it's easy to see why Keir Starmer's Labour party (and indeed the Greens) might suddenly have their tails up.
