The ex-partner of the self-described main suspect in the murder of Sophie Toscan du Plantier in west Cork in 1996 is suing Netflix over a documentary on the case.

Jules Thomas, from the Prairie, Schull in west Cork, is also suing the production company and the writer/director.

Ms Thomas lodged papers in the High Court office yesterday, signalling her intent to sue Netflix, production company Lightbox Media, and writer and director John Dower.

They were responsible for the three-part series, Sophie: A Murder in West Cork, which began streaming on Netflix last year.

According to the documents lodged, Ms Thomas is representing herself in the proceedings.

Ms Thomas separated from Mr Bailey last year.

Mr Bailey was arrested twice by gardaí for questioning about the killing of Ms Toscan du Plantier.

The body of the 39-year-old French film producer was found at the gate of her remote home near Schull on Christmas Eve 1996.

Mr Bailey has repeatedly denied any involvement.

He was convicted of the murder in his absence by a court in France in 2019.
