Jeremy Corbyn is to meet New Zealand premier Jacinda Ardern - the emerging star of the international Left - for talks this weekend. The Labour leader will host Ardern after she returns from a retreat at Windsor Castle with her fellow Commonwealth heads of government.

During the New Zealand election campaign last year, the 37-year-old politician was portrayed as the saviour of the beleaguered left in the wake of the Brexit vote and the election of Donald Trump. At the time Corbyn declared: “Do it for all of us” in a video of support.

After an event on gender equality at City Hall today, Ardern told the Guardian that she planned to share how the New Zealand Labour party had managed a “reset” at the 2007 election after many years in opposition. She said:

We spent nine difficult years in opposition, we went through multiple leaders. We managed a reset at the last election. We spoke to the issues that I know New Zealand was concerned about: job security, decent health services, education, wages that weren’t moving relative to the cost of living.

However, asked what advice she could give Corbyn about pushing his party across the line to power, she said she would be “very wary” about telling other political parties what to do, when hers had only been in power for less than a year. “I’m always happy to share about our experience but it would always be different to another nation’s and another party’s,” she said.
