Measures proposed in the review, commissioned by the previous government and led by Conservative peer Baroness Gabby Bertin, are understood to include making it illegal to possess or publish pornography showing women being choked during sex.

After her appointment by Rishi Sunak’s government, Baroness Bertin made it clear she would not be approaching the topic from a prudish or disapproving position.

She will make 32 recommendations on what should be done about the “high-harm sector” of legal online pornography.

The review, due to be published later, is expected to argue that porn videos considered too harmful for any certificate in the offline world should be banned online.

Non-fatal strangulation is already an offence if someone does not consent but its depiction online is not illegal.

The review suggests pornography websites have normalised such behaviour in the real world, with violent and degrading material rife on mainstream platforms amid a “total absence of government scrutiny”.
