Deputies in the Italian parliament have voted unanimously to introduce the crime of femicide – the murder of a woman, motivated by gender – as a distinct law to be punished with a life sentence.

In a symbolic move, the bill was approved on the day dedicated to the elimination of violence against women worldwide.

The idea of a law on femicide had been discussed in Italy before but the murder of Giulia Cecchettin by her ex-boyfriend was a tragedy that shocked the country into action.

In late November 2022, the 22-year-old was stabbed to death by Filippo Turetta, who then wrapped her body in bags and dumped it by a lakeside.

The killing was headline news until he was caught, but it was the powerful response of Giulia's sister, Elena, that has endured. The murderer was not a monster, she said, but the healthy son of a deeply patriarchal society. They were words that brought crowds out across Italy demanding change.

Two years on, MPs have voted for a law on femicide after a long and passionately debated session of parliament. It makes Italy one of very few places to categorize femicide as a distinct crime.

Introduced by Prime Minister Giorgia Meloni, the law was backed by her own hard-right government, as well as opposition MPs. Many wore red ribbons or red jackets today to remember the victims of violence.

From now on, Italy will record every murder of a woman that is motivated by her gender as femicide.

Femicides will be classified, they will be studied in their real context, they will exist, Judge Paola di Nicola, one of the authors of the new law, said of its significance.

She was part of an expert commission that examined 211 recent murders of women for common characteristics, then drafted the femicide law.

Talking of such crimes as rooted in exasperated love or strong jealousy is a distortion – that uses romantic, culturally acceptable terms, the judge argues, surrounded by her research at her home in Rome.

Italy will now join Cyprus, Malta, and Croatia as EU member states that have introduced a legal definition of femicide in their criminal codes.

The Italian law will apply to murders which are an act of hatred, discrimination, domination, control, or subjugation of a woman as a woman, or that occur when she breaks off a relationship or to limit her individual freedoms.

Gino Cecchettin isn't sure such a law would have saved his daughter: her killer was sent to prison for life in any case. But he thinks defining and discussing the problem is important.

He now tours Italian schools and universities to talk to young people about Giulia and about respect. If we give them the right tools to handle their life they will not act as Filippo, he hopes.

Italy currently ranks 85th in the Global Gender Gap Index, almost the lowest of all EU states, with just over half all women in employment, to name just one issue.

Tuesday's mammoth session of parliament ended late in the evening in Rome with a final speech by a governing party MP vowing that violence against women will not be tolerated, will not go unpunished.

This shows that on the fight against violence against women, our country has a common political will, Judge Paola di Nicola argues, whilst accepting there's a long way still to go.
