The rally Saturday by far-right extremists dressed in black came as authorities clamp down on protesters banging saucepans against the government, with new restrictions put in place Monday to shield President Emmanuel Macron from the noise.

The march on Saturday through an upmarket Left Bank district of Paris saw several hundred men from far-right groups march with flags and chant slogans to commemorate the death of a far-right activist, Sebastien Deyzieu, in 1994.

The protest was authorised by city authorities, and police could be seen patrolling nearby.

Socialist Party senator David Assouline called on Interior Minister Gerald Darmanin to “explain yourself”.

“It’s unacceptable to have allowed 500 neo-Nazis and fascists to parade in the heart of Paris. Their organisations, the display of their ideology, slogans, insignias are as much an insult to the dead as an incitement to racial hatred,” he wrote on Twitter.

France marked its traditional May 8 public holiday on Monday to commemorate the victory of Allied forces over Nazi Germany in 1945 and the lives lost in the fight against fascism.

Ian Brossat, a spokesman for the Communist party, joked that “saucepans are clearly more dangerous than jackboots”.

Left-wing charity Attac also wrote that the far right “demonstrates their hatred with complete impunity in the centre of Paris while the state is seeking to outlaw saucepan-banging.”

Well-known intellectual Jacques Attali called the rally “intolerable.”

The Paris police department reacted on Monday by explaining that it did not have the legal powers to prevent a demonstration unless there was a “proven risk to public order”.

“Given that this demonstration had not caused any problems or public order issues during previous years, the Paris prefect was not in a position to take steps to ban it,” it said in a statement.

It referred to a previous attempt in January to stop a flaming-torch rally by the far-right “Paris Pride” group, which was overturned by a judge after an appeal by organisers.

Saucepan bans

Demonstrations were banned on Monday around the Champs-Elysees in Paris where Macron attended a May 8 ceremony at the Arc de Triomphe war memorial.

Police in eastern Lyon also outlawed demonstrations Monday near a war memorial where Macron was expected to pay tribute to French Resistance hero Jean Moulin.

An appeal from the CGT trade union was rejected by a local court.

Members of the government have been pursued by saucepan-banging protesters since Macron signed a deeply unpopular pension reform into law on April 15 that will raise the retirement age to 64 from 62.

The far-right demonstration in Paris on Saturday ended with participants chanting “Europe, youth, revolution”, the slogan of the violent GUD far-right student group that was influential in the 1990s, an AFP reporter said.

Two former GUD members, Axel Loustau and Olivier Duguet, who have previously worked closely with French far-right political leader Marine Le Pen, were photographed at Saturday’s rally, the Mediapart website reported Monday.

The interior ministry has banned a number of extremist anti-immigration groups in recent years, including Generation Identitaire and Zouaves Paris.
