Martha Mills died after failures in her treatment at King's College Hospital.

Martha’s mother, Merope, is calling for hospitals around the country to bring in "Martha's rule", which would give parents, carers and patients the right to call for an urgent second clinical opinion from other experts at the same hospital if they have concerns about their current care.

The government has said it will explore the introduction of Martha's rule in UK hospitals.

Today’s Nick Robinson spoke to Dr Sanjiv Sharma, Medical Director at Great Ormond Street Hospital and Matthew Taylor, Chief executive of the NHS Confederation. Nick Robinson also spoke to Sir Robert Francis, chair of the Francis Report and chair of the Freedom to Speak Up Review, published in 2015.
