Crowds of protesters and celebrators flooded the streets of Paris as French election results began pouring in on Sunday.

On Sunday, French Prime Minister Gabriel Attal announced his intent to resign after a far-left political coalition was poised to win a plurality of French parliamentary seats. The coalition had unexpectedly assembled before the snap elections began.

Tens of thousands of left-wing demonstrators gathered in Paris's Place de la République on Sunday night to celebrate the news. Prime Minister Emmanuel Macron's centrist coalition is projected to take second place.

The results were a huge upset for conservatives in France, who had hoped that Marine Le Pen's National Rally would take power.

The left-wing coalition, which is called the Popular Front, is made up of France's Socialist Party, the French Communist Party, a green political party called the Ecologists and France Unbowed.

The bloc has pledged to institute a number of measures if elected, including scrapping Prime Minister Emmanuel Macron's pension reform and working towards establishing "a right to retire" at 60 years old.

The coalition also pledges to increase wages for public sector employees, establish a wealth tax and raise France's minimum wage.
