I think european liberals would rather work with fascists than even collaborate with the left, let alone call themselves “left”… oh, wait, they do.
Macron is turbo economical liberalism, and he does everything he can to not be affiliated with the left.
He even dissolved the Assemblée Nationale (our Parliament), and when a left-wing coalition came out on top, which should have secured them the prime minister’s seat, Macron delayed the appointment for months trying to buy time for the right to secure an agreement with the far right, and ended up choosing a prime minister from a right-wing party who did had only 7% of votes.
