The result is a minor victory for the nationalist firebrand, who started the year eyeing the presidency and end up with just a handful of seats in the National Assembly, too few to form a parliamentary group and have role in setting the political agenda.
“We are the only force that will fight against the dilution of France,” Le Pen said in a televised statement, declaring victory.
After losing to Macron with 34 percent in May’s presidential runoff, Le Pen had vowed to make the National Front the main opposition.
With 15 seats, French parties can form their own group in parliament, which gives them a chance to lead committees and more time to question the government.
“There is no material progress for the National Front,” said Brice Teinturier, head of public opinion at pollster Ipsos.
