The Netherlands’ parliament on Tuesday narrowly voted against a multibillion-euro European Union defense plan presented by Dutch Prime Minister Dick Schoof last week.

The motion was introduced by the right-wing populist JA21 party, also known as the Conservative Liberals.

It was supported by three of the four coalition parties. The motion passed in a 73-71 vote, with the opposition Socialists (SP) also voting in favor.

Though the motion is not legally binding, it raises uncertainty about how the government will proceed.
