In a tearful announcement, New Zealand Prime Minister Jacinda Ardern announced that she is resigning from her position.

Id be doing a disservice to New Zealand if I continued, she said while speaking Thursday local time at the Labour Party caucus retreat in Napier, New Zealand.

She will conclude her term no later than Feb. 7. The general election for her replacement is set for Oct. 14.

Ardern, who made history in 2017 when she became the worlds youngest female head of government at age 37, said she realized in recent months she no longer had the energy for the demanding job.

I believe that leading a country is the most privileged job anyone could ever have but also one of the more challenging, she said during the announcement, according to New Zealand public broadcaster RNZ . You cannot and should not do it unless you have a full tank plus a bit in reserve for those unexpected challenges.
