How old is the new president of france

I think there may be some confusion here!

As of my knowledge cutoff, the current President of France is Emmanuel Macron, who was first elected in 2017 and re-elected in 2022. He was born on December 21, 1977, which makes him 45 years old (as of March 2023).

If you're referring to a hypothetical new president of France, I'd be happy to help you with that information once it's available!
