A Northern Ireland politician targeted in a deepfake video four years ago has said she is quitting Elon Musk's social media site X due to what she described as a "complete negligence in protecting women and children online".
Cara Hunter of the Social Democratic and Labour Party (SDLP) said her decision was due to growing concerns over deepfake imagery produced by the site's AI tool Grok.
Ofcom has opened a formal investigation into X to see whether it has complied with its duties to protect people in the UK from illegal content.
Technology Secretary Liz Kendall has said she would back Ofcom if it blocks UK access to X but Musk has said critics are seeking "any excuse for censorship."
In a statement Ofcom said it had "urgently" made contact with X and "set a firm deadline of Friday 9 January for it to explain what steps it has taken to comply with its duties to protect its users in the UK".
