France's highest administrative court is allowing journalists to access files regarding former President Nicolas Sarkozy's winning presidential campaign in 2007, which is suspected of having received illegal funding from Libyan leader Moammar Gadhafi's regime.

France's Council of State on Friday asked the commission in charge of controlling the campaign funds to release details of its written exchanges with Sarkozy and his treasurer, according to a new law guaranteeing free access to administrative documents.

The investigative news website Mediapart had initially sought the files. The commission refused, and Mediapart appealed the decision.

Sarkozy was handed preliminary charges in an investigation into allegations that he took 50 million euros ($54.5 million) in illegal campaign funds from the late Libyan leader. He has denied any wrongdoing.
