What voters liked about her: Youthful, confident and credited with having the X-factor that was desperately needed to turn the Labour party into a real contender for power after nine years of a National government.

What they didn’t: Inexperienced and untested.

Potential problems: Australia’s foreign minister, Julie Bishop, has said it would be “very difficult to build trust” with a Labour government in New Zealand, accusing the party of collaborating in a plot to destabilise the Australian government after it emerged that the Australian deputy prime minister held dual Australian/New Zealand citizenship.

Made international headlines when ... Ardern called out sexist questions – about any plans to have a baby – that emerged just hours after she became Labour leader. She said such treatment of women was “unacceptable”.

In her spare time: Likes to DJ.

Interestingly ... Was brought up as a Mormon but left the church over its anti-homosexual stance. Doesn’t drink coffee.
