In a politically charged atmosphere, the left-wing movement La France Insoumise is rallying support for Lucie Castets as the next Prime Minister of France.

During their summer gathering in Valence, party members expressed their belief that President Emmanuel Macron will have no choice but to appoint Castets to Matignon.

Meanwhile, Castets, a relatively unknown high-ranking official until recently, has been gaining momentum across various leftist summer events, including a significant appearance at the Ecologists' summer days in Tours.

Her presence has sparked enthusiasm among thousands of attendees, who see her as a unifying figure for the left.

The political climate is tense, with Jean-Luc Mélenchon's movement threatening to demand Macron's resignation if he does not appoint a leftist leader.

As the political landscape shifts, all eyes are on Macron's next move, which could redefine the balance of power in France.
