Report: Apartment used for French President's affair linked to the mob

French media is reporting that the apartment used by President Francois Hollande for his alleged affair with an actress is linked to the mafia.

It has been reported that actor Julie Gayet has been borrowing the apartment from a friend who was involved with two Corsican mobsters.

Mr Hollande's partner Valerie Trierweiler remains in hospital today for treatment after being admitted for being shaken by reports of the affair.

The President has threatened to sue tabloid magazine 'Closer' over the allegation.
