Paris | French Prime Minister Gabriel Attal has announced he will resign after a broad left-leaning coalition took the most seats in Sunday's runoff parliamentary election.

The New Popular Front fell short of a majority but surged ahead of the far-right National Rally, which placed third behind the centrist party of President Emmanuel Macron. Voter turnout was high.

The outcome leaves France facing the stunning prospect of a hung parliament and threatens political paralysis in a pillar of the European Union and Olympic host country.
