Two-year-old Isla is believed by medical experts to be the only person in the world living with a genetic condition that accelerates the ageing of her cells.

University Hospitals of Leicester NHS Trust said it was "very sorry Isla's parents have concerns about her care in our hospitals. We urge them to contact us directly if they have ongoing concerns."
