昨日の夜、やっと決まりました、はい、そうです、労働党[ろうどうとう](= Labour Party)が政権[せいけん] (= government)をとることになりました。ジャシンダ・アーダーンさんは、労働党[ろうどうとう]の党首[とうしゅ](= party leader)に数か月前になったばかり、そして、今度はニュージーランドの首相[しゅしょう](= prime minister)になります。37歳の若き首相です!
We finally found that which party would form a government – the New Zealand Labour party! Jacinda Ardern, the party leader, landed the party's leadership position just a few months ago and now she will be the prime minister of New Zealand! A full-of-energy 37 yr old PM will be born!
Note: Labour Party used a slogan 'Let's do this' during its election campaign.
