Thirty-seven-year-old Jacinda Ardern was only elected as leader of New Zealand last month, but she’s already taking on the world.

Ardern recently met US president Donald Trump at a trade summit Vietnam. As the world leaders were stood waiting to go in to dinner, Trump joked to someone stood near him that Ardern (“this lady” as he called her) had “recently caused a lot of upset in her country”. He was referencing the fact that the New Zealander was only elected as leader of the Labour party seven weeks before the national election that brought her to power so unexpectedly.

Here comes the best bit. In an interview with Newsroom, Ardern says she turned around to Trump and quipped back: “No-one marched when I was elected.” BOOM.

Ardern said the president brushed the comment off as a joke, but judging by Trump’s track record of taking offence at literally everything, we wouldn’t be so sure.

Remember Trump’s obsession with proving he didn’t have tiny hands, for example? Twitter does.
