King Willem-Alexander swore in a new minority coalition government on Monday, appointing Rob Jetten as prime minister.

Jetten, of the pro-EU D66 party, is the youngest-ever and first openly gay prime minister in the Netherlands.

His coalition includes the center-right Christian Democrats and right-wing VVD, but holds only 66 of 150 lower house seats and lacks a Senate majority, requiring opposition support for legislation.

Jetten, first elected to parliament in 2017, previously served as a cabinet minister under former Prime Minister Mark Rutteand championed major climate legislation, the DW has reported.

He is engaged to Argentine Olympian Nicolás Keenan.
