Currently, Macron's camp maintains that they cannot form a government with members of "France Unbowed" (LFI), the primary left-wing party and an integral component of the "New Popular Front" coalition. Although Lucie Castets does not hail from LFI, certain ministerial positions may be filled by individuals affiliated with this party.
Macron has been demonizing LFI in a very similar fashion to the way Corbyn was demonized in the UK, with accusations of antisemitism for their support of Gaza.
