The UK government said it will bring an amendment to its Crime and Policing Bill following a campaign by backbench Labour PM Jessica Asato and others.

An independent review commissioned by the previous Conservative government had found that media sources including pornography had established strangulation during sex as a “sexual norm”.

Alex Davies-Jones, the UK government’s minister for victims and tackling violence against women and girls, said: “Depicting strangulation during sex is not only dangerous, but also degrading, with real-life consequences for women.

“Cracking down on the appalling rise of strangulation pornography will protect women and send a clear signal to men and boys that misogyny will not be tolerated.”

The government says the amendment will build on the Obscene Publications Act 1959, and the Criminal Justice and Immigration Act 2008 which criminalises the possession of extreme porn.

The Ministry of Justice has been contacted for clarity about whether the changes will also apply in Northern Ireland.
