Guillaume Tabard in Le Figaro, a conservative daily, produced some modelling based on the European results. He made adjustments for the legislative elections when candidates winning the support of more than 12.5 per cent of registered voters in the first round go to a run-off.

The calculations are astonishing. The far-right bloc (RN and the smaller Reconquête) are in the lead in 362 seats. The left, which crucially has formed a “popular front” spanning anti-capitalist radicals and social democrats, is ahead in 211. Macron’s centrist bloc is ahead in only three (all of them seats for French people abroad) and the centre-right in one, the wealthy 16th arrondissement in Paris.
