There have been wild scenes across France after Sunday’s unexpected election result in which a leftist alliance saw off a predicted win by the far right.

France faces potential political deadlock after the vote, with no group winning a majority.

Voters delivered a major setback for Marine Le Pen’s nationalist, eurosceptic National Rally, which opinion polls had predicted would win the second-round ballot but ended up in the third spot, according to pollsters’ projections.

The results were also a blow for centrist President Emmanuel Macron, who called the snap election to clarify the political landscape after his ticket took a battering at the hands of the RN in European Parliament elections last month.

He ended up with a hugely fragmented parliament, in what is set to weaken France’s role in the European Union and elsewhere abroad and make it hard for anyone to push through a domestic agenda.

The election will leave parliament divided in three big groups – the left, centrists, and the far right – with hugely different platforms and no tradition at all of working together.

What comes next is uncertain.

The leftist New Popular Front (NFP) alliance – which wants to cap prices of essential goods such as fuel and food, raise the minimum wage, hike wages for public sector workers and impose a wealth tax – immediately said it wanted to govern.

“The will of the people must be strictly respected … the president must invite the New Popular Front to govern,” said hard-left leader Jean-Luc Melenchon.

The RN has worked under Le Pen to shed a historic reputation for racism and antisemitism but many in French society still view its France-first stance and surging popularity with alarm.

The awkward leftist alliance – which the hard left, Greens and Socialists hastily put together before the vote – was far from having an absolute majority of 289 seats in the 577-seat assembly.

Official results were trickling in, with the results from most, if not all, constituencies likely early on Monday, local time.

Polling agencies – which are generally accurate – forecast the left would get 184 to 198 seats, Macron’s centrist alliance 160 to 169 and the RN and its allies 135 to 143.

Prime Minister Gabriel Attal said he would hand in his resignation on Monday but would stay on in a caretaker capacity as long as needed.

A key question is whether the leftist alliance will stay united and agree on what course to take.

Melenchon, leader of the hard-left France Unbowed (LFI), ruled out a broad coalition of parties of different stripes.

Raphael Glucksmann, from the Socialist Party, urged his alliance partners to act like “grown-ups.”

“We’re ahead, but we’re in a divided parliament,” he said. “We’re going to have to talk, to discuss, to engage in dialogue.”

The constitution does not oblige Macron to ask the leftist group to form a government, though that would be the usual step as it is the biggest group in parliament.

In Macron’s entourage, there was no indication of his next move.

“The question we’re going to have to ask ourselves tonight and in the coming days is: Which coalition is capable of reaching the 289 seats to govern?” one person close to him told Reuters.

Some in his alliance, including former prime minister Edouard Philippe, envisaged a broad cross-party alliance but said it could not include the far-left France Unbowed.

For the RN, the result was a far cry from weeks during which opinion polls consistently projected it would win comfortably.

The left and centrist alliances co-operated after the first round of voting last week by pulling scores of candidates from three-way races to build a unified anti-RN vote.

In his first reaction, RN leader Jordan Bardella called the co-operation between anti-RN forces a “disgraceful alliance” that he said would paralyse France.

Le Pen, who will be the party’s candidate for the 2027 presidential election, said however that Sunday’s ballot, in which the RN made major gains compared with previous elections, had sown the seeds for the future.

“Our victory has been merely delayed,” she said.

Voters punished Macron and his ruling alliance for a cost-of-living crisis and failing public services, as well as over immigration and security.

Le Pen and her party tapped into those grievances, spreading their appeal way beyond their traditional strongholds along the Mediterranean coast and in the country’s northern rust belt, but it was not enough to win power.
