By Elizabeth Pineau and Michel Rose PARIS (Reuters) -French Prime Minister Francois Bayrou on Tuesday opened the door to renegotiating a disputed pension reform in a bid to win over left-wing lawmakers he needs to pass the 2025 budget.

French Prime Minister Francois Bayrou on Tuesday warned parliament about his country's spiralling debt and said he was ready to reopen talks on pension reform, hoping to avoid defeat in any no-confidence vote that could prolong the country's rumbling political crisis.

France's new Prime Minister François Bayrou has given labour groups three months to devise a fairer pension plan to replace the controversial reform pushed through by President Emmanuel Macron in 2023.
