A Scots mum says tech bosses should be made criminally liable for protecting kids from online harm - after her teen daughter took her own life.
Ruth Moss, 51, is campaigning for tougher social media regulations and new legislation which would hold tech bosses to account.
Her daughter Sophie Parkinson, 13, died at home in Angus, Fife, in 2014, after she had viewed suicidal and self-harm posts on social media.
