Will the Socialist Party implode?

Will the Socialist Party implode

This weekend was marked in France by the birth of the “New popular ecological and social union” (Nupes) led by the rebellious France of Jean-Luc Mélenchon. An alliance resulting from the agreement concluded a few days earlier with several leftist forces and in particular the Socialist Party. Comments (and criticisms) are rife about such an alliance: will the PS come out a winner? What does this agreement say about socialist ideology today? And what future after the legislative elections?
