Far-right lawmaker Geert Wilders pulled his Freedom Party out of the Netherlands’ ruling coalition, causing the government to collapse and triggering a snap election.

Wilders left over the refusal of his three coalition partners to agree to his plans to curb migration, which included closing the border to asylum seekers, temporarily halting family reunification and returning asylum seekers to Syria. He wrote on social media Tuesday that his party “is leaving the coalition.”

The AEX Index, a gauge tracking the 25 largest stocks listed on the Euronext Amsterdam, fell as much as 0.5 percent before paring some of the loss.

Wilders’ move automatically triggers a new ballot, which otherwise would have been held in 2027.

This isn’t the first time migration sunk a Dutch government: In 2023 the government of the previous prime minister, Mark Rutte, who had been the country’s longest-serving leader, collapsed over the same issue.

Wilders’ party delivered a shock electoral victory in the 2023 parliamentary vote as far-right parties across Europe rose in popularity, partly on promises to cut migration. The Dutch coalition parties, however, refused to name Wilders prime minister, instead tapping former spy chief Dick Schoof, who didn’t hold a party affiliation.

Even though the Freedom Party’s support had been declining over the past few months, it regained its position as the strongest political force in a leading poll this week after Wilders announced his new migration plan.
