Jacinda Ardern
On 19 January 2023, Ardern announced she would resign as Labour leader and prime minister before 7 February. She said the reason for her resignation was to spend more time with her family. Her announcement was a surprise because a few months ago she said she would lead the Labour party into the 2023 general election. In some opinion polls, Ardern's popularity had reached all-time lows in the past few months.
