The result represents a considerable decline for the once golden boy president who convinced more than 60 per cent of voters to cast their ballots in his favour less than six months ago.
The poll, conducted by YouGov for Huffington Post and the French TV channel CNews, found just 32 per cent of voters now hold a “positive view” of the 39-year-old head of state, slightly up from 30 per cent in September.
Centrist voters are behind this slight boost in his approval rating: 90 per cent of those surveyed who identified themselves as centrists said they held a “favourable opinion” of Mr Macron when asked by pollsters what they thought of their new leader – up from 75 per cent in September.
Republicans, are growing increasingly dissatisfied with the En Marche! leader’s performance: only 32 per cent of those polled who identified themselves as centre-right Republicans said they held a favourable opinion of their head of state, down 13 percentage points in one month.
Mr Macron’s conservative prime minister Édouard Philippe is also struggling to win over the French.
When asked by YouGov pollsters what opinion they held of Mr Philippe, 34 per cent said they held a “favourable view” of him, up two percentage points in one month.
Although Mr Philippe is less popular than Mr Macron among centrists, he is significantly more favoured among right-wingers.
Eighty-four per cent of those who identified as centrists said they held a favourable opinion of Mr Philippe.
Among those who identified as right-wing Republicans, however, close to half – 47 per cent – said they held a favourable opinion of him.
But the government’s approval rating remains tepid: only 29 per cent of respondents told YouGov pollsters they held a favourable opinion of Mr Macron’s ‘all-stripes’ cabinet.
Mr Macron, a former economy minister under Socialist president François Hollande, said after his landslide victory in May that he planned a ‘Jupiterian’ presidency: he pledged to be a dignified leader, like the Roman god of gods, and weigh his rare pronouncements carefully.
But his aloof style of governing and determination to press ahead with his tough reform agenda despite growing public dissent has turned the tide of public opinion against him, and dented his approval ratings.
The poll was carried out online on September 27-28 among 1,002 people.
