France’s finance minister said on Monday that the snap election called by President Emmanuel Macron after a bruising loss to the far-right in European Parliament elections would be the most consequential legislative vote in the republic’s history.

Macron’s shock decision amounts to a roll of the dice on his political future. It could hand a great deal of power to Marine Le Pen’s far-right National Rally (RN) after years on the sidelines, and neuter his presidency three years before it is due to end.

The legislative vote will take place on June 30, less than a month before the start of the Paris Olympics, with a second round on July 7.

“This will be the most consequential parliamentary election for France and for the French in the history of the Fifth Republic,” Finance Minister Bruno Le Maire told RTL radio.

A source close to Macron said the president hoped to mobilize voters who had abstained from voting on Sunday.

“We’re going for the win,” the source said. “There’s audacity in this decision, risk-taking, which has always been part of our political DNA.”
