Billionaire Elon Musk, the owner of social media network X, poses a threat to democracies, French Prime Minister Francois Bayrou said on Monday.

"Elon Musk is creating a threat to democracies," Bayrou said in a local TV interview. "Money should not give the right to rule consciences."

His comments about Musk come after he warned last week that France and Europe as a whole would have to stand up to US President Donald Trump and his policies or risk being "dominated ... crushed ... marginalized."
