French President Emmanuel Macron has dissolved the country's National Assembly and called a snap election after his party suffered a bad result in elections to the European Parliament.
Marine Le Pen's hard-right National Rally party won about 32% of the vote - a 10 point increase on the last EU election in 2019.
It is more than double the 15% taken by Mr Macron's centrist, pro-European Renaissance Party, according to exit polls.
Mr Macron said he could not "pretend nothing had happened" and admitted the EU election was "no good" for his government.
The "rise of nationalists" is a danger to France and to Europe, he said in an address to the country on Sunday.

Speaking at the Élysée Palace in Paris, Mr Macron said: "I've decided to give you back the choice of our parliamentary future through the vote.
"I am therefore dissolving the National Assembly."
There will be two rounds of voting on June 30th and July 7th, he added.
"I have heard your message, your concerns, and I will not leave them unanswered," Mr Macron said.
"France needs a clear majority in order to act with serenity and harmony."
Ms Le Pen said her party was "ready to take over power if the French give us their trust in the upcoming national elections".
She added: "We are ready to put the country back on its feet. We are ready to defend the interests of the French people. We are ready to put an end to mass immigration."
European results
A similar move to the right is underway in Germany too.
The Alternative for Germany party (AfD) appears to have taken second place in EU elections there, while Chancellor Olaf Scholz's Social Democrats recorded their worst ever result, falling to 14%.
Projections showed the AfD's vote had risen to 16.5% - up from 11% in 2019.
Its gains appear to have come from young people in particular.
Co-leader Alice Weidel said her party had done well because "people have become more anti-European".
She added: "People are annoyed by so much bureaucracy from Brussels."
The centre-right Christian Democratic bloc of EU Commission President Ursula von der Leyen dominated in Germany with almost 30%.
It appears to have been a disappointing election for Green parties.
In Germany, they are predicted to fall from 20% to 12%, while further losses are expected in France and several other EU nations.
Some 373 million Europeans across all 27 EU countries were eligible to vote - and they have elected 720 representatives.
Members take their seats in Brussels in mid-July.
