Philippe is reported to be hoping for a Bardella candidacy, because he reckons the 30-year-old’s inexperience will soon begin to tell, whereas Le Pen, 57, is a tough election warrior with a deep rapport with voters across the country.

The RN is a nationalist party which wants to limit immigration, for example by stopping families from joining migrant workers and ending the right to nationality for all born on French soil. Officially at least, the party wants to bring down the age of retirement to 62.

As for the hard-left France Unbowed (LFI), its leader Jean-Luc Mélenchon declared himself a candidate earlier this month, with a promise among his first acts as president to dismantle the media empires of French billionaires like Vincent Bolloré.

Calling for hefty new taxes on big business and an opt-out from EU rules, the 70-year-old former minister has built a formidable support base in the “new France” of the high-immigration banlieues – the suburbs of French cities – and among the prospect-deprived, university-educated young.

As a candidate in 2022, he came within an ace of qualifying for the second round against Emmanuel Macron, and believes his destiny is to face off against the far right. “When the rest are gone, it’ll be me and her,” he has said.

But in that “battle of the extremes” – populist left versus populist right – for the presidency of the French republic, all polls suggest that there would be one clear winner: and it is not Jean-Luc Mélenchon.
