Engulfed in an unfolding domestic political scandal, President Macron is also lurching toward the year’s end by alienating many erstwhile partners on the Continent with his recent remarks about Russia. While neither circumstance is enough to dislodge the middle-aged maverick from his presidential perch, taken together they are dimming his shine at Paris and undercutting his waning influence on the global stage. 

Mr. Macron’s credibility as a French leader of stature is increasingly compromised by a pair of high-level investigations into the funding of his 2017 and 2022 election campaigns. The probes also implicate an American consulting firm, McKinsey and Company, into which France’s financial public prosecutor opened a probe for alleged tax fraud in March.
