Ian Bailey says he hopes a cold case review will finally clear him of the murder of Sophie Toscan du Plantier.
The Gardai announced the inquiry yesterday - over 25 years after the French film-maker was killed near Schull in west Cork.
Mr Bailey was never charged with her murder in Ireland, but was convicted in his absence in Paris.
The former journalist says he'll co-operate with the review - and hopes it makes progress.
"I would hope that there would be an acknowledgement, if not the discovery of who it was the murderer of Madame Sophie Toscan du Plantier, an acknowledgement that it wasn't me.
"That's my hope. Any assistance I can give to an Garda Síochána I will be giving."
