Judges in the French city of Avignon will hand down verdicts on 51 men on Thursday in a mass rape trial that has turned a 72-year-old woman into a feminist icon.

For almost a decade, Gisèle Pelicot was drugged by her ex-husband Dominique, who then invited dozens of men he had recruited online to have sex with her in her bed at home while she was unconscious and unaware.

It was her decision to waive her anonymity and throw this trial into the open - in her words, making "shame swap sides" from the victim to the rapist.

Although he admits the charges against him, most of the other men on trial deny what they did was rape.

Prosecutors have asked for jail sentences ranging from four years to 20 years, the maximum sentence for a charge of aggravated rape.

One of the defendants, who has admitted the charges, has said the trial was rushed and "botched".

Campaigners say this case proves the need for consent to be built into France's rape laws, as in other European countries.

From 2011 to 2020, Dominique Pelicot plied his wife with tranquilising drugs and sleeping pills without her knowledge, crushed them into powder and added them to her food and drink.

Gisèle Pelicot suffered memory loss and blackouts because of the drugs and she has spoken of 10 years of her life that have been lost.

He was eventually caught because a security guard reported him to police for taking photographs under women's skirts in a supermarket.

"I thought we were a close couple," she once told the court. Instead, her husband was going on a notorious but now banned website called Coco.fr to invite local men to their home to have sex with her while she was comatose.

"I was sacrificed on the altar of vice," Gisèle Pelicot said early in the trial.

Since the start of September, Judge Roger Arata and his four colleagues have heard how 50 men, now aged between 27 and 74, visited the Pelicots' home in the village of Mazan. (BBC)
