The chances are your child has a smartphone. But whether they're allowed to use them in school or not could have a huge impact on not only their academic success but also mental health issues and wider threats to their wellbeing.

Brianna Ghey was 16 when she was stabbed to death by two 15-year-olds after being lured into a park in Warrington. Her mother, Esther, says she lost her daughter twice - firstly to her phone, then to her killers.

Esther now wants a legal ban on phones in schools, rather than the current guidelines which don't make such a ban compulsory.

In today's episode, Kamali Melbourne speaks to our North of England correspondent, Shingi Mararike - following his interview with Esther Ghey - as well as campaigner, Dr Susie Davies, who would like to see even stronger measures to protect young people from the dangers of mobile phone use.
