The singer has found herself at the centre of a debate over female representation in music after she, as the only woman on the album of the year shortlist, was also the only nominee not asked to perform solo on the night.

Of the 13 women, six are heads of European countries, two are heads of South American countries and four are their country’s first female leaders. Europe counts the most women in power.

Marshall Islands president Hilda Heine is Ardern’s only female counterpart in the Asia-Pacific region and is relatively new to the job, having served just over a year.
