It depends. "En Marche" has promised to present new candidates, civil society etc. but often, incumbent MPs have declared their support... in Lyon, several PS have defected to Macron, and logically will get the endorsement.

Then there is the fact that both the Insoumis and the Communist Party are running candidates, against each other, for the legislatives. There will also be an official PS (actually, PS/EELV alliance) candidate, everywhere. Unless.
