Martha's rule: Mother calls for right to second opinion

The family of a 13-year-old girl who died of a sepsis infection are calling for patients and their loved ones to be given the right to ask for an urgent second opinion.

Martha Mills died two years ago when doctors failed to spot and treat her condition early enough.

Martha's mother, Merope, told BBC Radio 4's Today programme she wants hospitals around the country to bring in "Martha's rule", which would give parents, carers and patients the right to ask for an urgent second opinion from a critical care team at the same hospital - if they have concerns about their current care.
