What the article says is that the French police is investigating what group or individual is behing the sending in March 2007, the week before Sarkozy's election, of a forged, anonymous email alleging Sarkozy's ties with the Mossad during the early 80's. Nobody ever seriously suspected Sarkozy of anything, except perhaps the usual suspects at the Tehran Times, Al-Ahram, Pravda and all other purveyors of conspiracy theories. A far cry from your characterization that "Le Figaro reported that french police are investigating Sarkozy`s alleged links with Mossad". In fact, just the opposite since french police are inclined to believe this was a right-wing agitprop move.
