Francois Bayrou has been appointed as France's new prime minister amid significant challenges, including a credit rating downgrade by Moody's and a politically fragmented environment. The controversial previous government, led by Michel Barnier, lasted only three months due to a lack of legislative support. Bayrou’s centrist stance has raised expectations for a coalition that might stabilize the political scene, but critics doubt his ability to unify divided parties and tackle France's mounting debt and budget deficit. The country's public finances are under scrutiny, with the potential for further downgrades looming in light of ongoing instability.
