The young leader’s tactless handling of a scandal involving his top bodyguard also dented his credibility with voters, throwing into doubt his promise of building an exemplary Republic.
The poll, conducted by Odoxa for France Inter, la presse régionale and newspaper L’Express, showed that just 29 percent of French people have a “favourable” opinion of the 40-year-old centrist, down 12 percentage points from Odoxa’s previous survey in June.
This is the lowest score recorded by Odoxa pollsters since his election in May 2017.
Seventy-one per cent of respondents have an “unfavourable” opinion of Mr Macron, the poll showed, up 12 percentage points from June.
Conservative Prime Minister Edouard Philippe is also struggling to build support among French voters: 35 percent of those polled said they had a favourable opinion of Mr Philippe, compared with 64 percent who said they had an unfavourable opinion.
Jérôme Jaffré, the director of the Cecop polling institute, said in an interview with the French daily Le Figaro published on Monday: “Macronism is a pyramid that rests on its tip. The decision-making process seems to be centred around Mr Macron alone. Its base is too narrow and too dependent on the head of state to make room for criticism [of the president].”
Seemingly oblivious to his plummeting approval ratings, Mr Macron remains determined to put an awkward summer behind him and push ahead with his ambitious reform plans.
His clumsy response to a scandal that broke when his then senior bodyguard was filmed assaulting a May Day protester drew bitter criticism from his opponents, who denounced his aloofness and accused him of breaking an election promise to reinforce rules of ethics and transparency in the political sphere.
But the incident could also affect support for the next batch of reforms, which include a revamp of the constitution, controversial plans to restructure the outdated welfare system and an overhaul of the way the French pay their income tax.
The centrist government is also looking for ways to reduce the budget deficit and patch up the strained pension and public healthcare systems.
The Odoxa poll was conducted among 1,004 people between September 5 and September 6.
