PARIS, Oct 23 (Reuters) - The number two executive at TF1 (TFFP.PA) is leaving France's largest commercial television group after months of conflict with chief executive Nonce Paolini over the group's strategy.

General director Axel Duroux is leaving the company today, TF1 said. It cited strategic differences as the reasons for Duroux's departure.

"TF1 and Axel Duroux decided by mutual agreement to terminate their collaboration because of strategic differences regarding the management of the company," TF1 said in a statement on Friday.
