A French woman jailed for killer her abusive husband has been pardoned by French President Francois Hollande.

Here's what we know about Jacqueline Sauvage's case.

Ms Sauvage, 69, said her violent alcoholic husband Norbert Marot raped and beat her and her three daughters as well as her son during their 47-year marriage.

A day after her son hanged himself in September 2012, Ms Sauvage shot her husband three times in the back with a rifle.

She was found guilty of murder and sentenced to 10 years in prison in October 2014.

Her conviction was upheld on appeal in December 2015 after state prosecutors rejected her plea of self-defence.

During her trial, Ms Sauvage's daughters spoke of their fear their father w

“We were afraid of him, he terrified us,” one said.

Another, who was raped at the age of 16, said her father's death was a "relief".

Her case sparked outrage in France, with more than 400,000 people signing a petition calling on Mr Hollande to intervene.

Her daughters - who throughout the trial described the terror and fear inflicted on them by their father - have long campaigned for their mother to be freed.

"Faced with exceptional human circumstances, the President of the Republic wished to enable Ms Sauvage to be reunited with her family as quickly as possible," a statement from Mr Hollande's office said.

The move does not quash her conviction but it does reduce the 69-year-old's sentence and allows her to potentially leave in mid-April.

The gesture came two days after the president met Ms Sauvage's three daughters for the first time.

Yes, once before.

In 2013 he granted a sentence reduction to allow Philippe El Shennawy, then France's longest-serving prisoner, to be freed on parole after 38 yearsin jail.
