An inquest into the death of a baby girl following a 26-minute ambulance wait is due to be held.
Seventeen-week-old Bella Hellings died at her home in Thetford, Norfolk, after suffering a fit on March 11.
Her mother, Amy Cater, said it took 26 minutes for an ambulance to arrive, more than three times longer than emergency response targets dictate.
The baby was taken to West Suffolk Hospital in Bury St Edmunds but later died.
The East of England Ambulance Service has carried out a review into the incident but this is yet to be made public.
National guidelines state that an emergency response vehicle should reach 75% of patients deemed to be in a life threatening condition within eight minutes.
An inquest is due to be held at Norfolk Coroner's Court in Norwich this morning.
