PARIS - President Nicolas Sarkozy's office is denying a claim by Moammar Gadhafi's son that the French leader received funding from Libya for his election campaign.

Seif al-Islam Gadhafi has told Lyon, France-based EuroNews television that "we have all the details and we are ready to reveal everything" about his country's financing of Sarkozy's campaign in 2007.

Gadhafi made the comments after being asked his opinion of Sarkozy, who has led the diplomatic push for tough action against the Libyan regime in its battle against rebel fighters.

A Sarkozy spokesman, who declined to be identified by name because of presidential Elysee Palace policy, said Wednesday: "The Elysee denies" the claims by Gadhafi.
