The UK media regulator has set out new rules for social media companies designed to keep children safe online.   The new Ofcom rules include age verification and reformulating algorithms to keep children away from "toxic" content. But parents whose children have died as a result of exposure to harmful content have called the rules an "insult". On the Sky News Daily Niall Paterson is joined by technology correspondent at the Financial Times Cristina Criddle to discuss what the measures are and how they can be delivered.   Niall is also joined by John Carr, who is on the government's principal advisory body for online safety and security for children, to discuss the challenges of enforcing the rules and if they go far enough to protect children.    Producers: Soila Apparicio, Emma Rae Woodhouse Promotions producer: David Chipakupaku Editor: Paul Stanworth
