INVESTIGATION and INQUEST

On 19 October 2023 I commenced an investigation into the death of Mabel Olivia
Williams, who died when she was 6 days old.  The investigation
concluded at the end of the inquest on 15 August 2025.  The medical cause of
Mabel’s death was 1a) Severe hypoxic ischaemic encephalopathy, 1b)
Undiagnosed uterine rupture.

Mabel’s mother, 
caesarean section.  During the period before Mabel’s birth 
was for vaginal birth, but she was particularly anxious about pregnancy and birth,
fearful that she might lose Mabel, and keen to pursue the safest option she could
for her unborn daughter.

 was warned antenatally that if she trialed vaginal birth after caesarean

section (VBAC) she might experience “uterine rupture” or “uterine scar rupture”,
but at no point was she told what that phrase actually meant, how severe

child (or indeed for her).

she was started on synthetic oxytocin without being counselled that this further

distress and ultimately a fatal hypoxic episode for Mabel, who was born alive but
died 6 days later.

My conclusion at the end of the inquest was that “Mabel died because numerous
indicators of her own distress, and of the increasing severity of her mother’s
clinical condition, went unrecognised by the midwifery staff involved in her care
or were not conveyed to the clinical team in time to expedite her birth safely.
Neglect contributed to Mabel’s tragic death.”

I was also very concerned that appropriate steps had not been taken to ensure
 understood the nature of one of the most significant risks of VBAC.

6 days later in the Neonatal Intensive Care Unit of a hospital in Bristol.

CORONER’S CONCERNS

During the course of the inquest the evidence revealed matters giving rise to
concern. In my opinion there is a risk that future deaths could occur unless
action is taken. In the circumstances it is my statutory duty to report to you.

The MATTERS OF CONCERN are as follows.  –

was advised about VBAC she was referred to internal guidance

When 
from the hospital and to the RCOG’s information leaflet “Birth options after
previous caesarean section” (published in July 2016).  I reviewed the information
leaflet and it does not contain any indication that uterine rupture could potentially
prove fatal for mother and / or baby.  My concern is that prospective parents may
rely on this information leaflet to assist them in making informed choices about
their birth options, and that if the risk is not identified then other patients like

 might pursue VBAC in circumstances where – if they had understood the

risk better – they would have chosen otherwise.

ACTION SHOULD BE TAKEN

In my opinion action should be taken to prevent future deaths and I believe you
and/or your organisation have the power to take such action.

Dear Mr Sowersby  

Re: Baby Mabel Olivia Williams  

Thank you for your Regulation 28 Report to Prevent Future deaths following the inquest into the 
death of Baby Mabel on 8 September 2025.  

The loss of a baby is a devastating tragedy for parents, the wider family, and healthcare 
professionals involved. We would like to begin by extending our deepest and heartfelt condolences 
to Mabel’s family for their profound loss.  

This response has been developed following input from members of the Royal College of 
Obstetricians and Gynaecologists (RCOG) Patient Safety Committee and Senior Officers of the 
College.   

We recognise and respect the narrative conclusion from the inquest. The medical cause  
of Mabel’s death was: 

1a) Severe hypoxic ischaemic encephalopathy,   
1b) Undiagnosed uterine rupture.   

We also recognise the matters of concern as outlined in your letter as follows,   
When Becky (Mabel’s mother) was advised about VBAC she was referred to internal guidance from 
the hospital and to the RCOG’s information leaflet “Birth options after previous caesarean section” 
(published in July 2016). I reviewed the information leaflet and it does not contain any indication that 
uterine rupture could potentially prove fatal for mother and / or baby. My concern is that prospective 
parents may rely on this information leaflet to assist them in making informed choices about their 
birth options, and that if the risk is not identified then other patients like Becky might pursue VBAC in 
circumstances where – if they had understood the risk better – they would have chosen otherwise.  

 
 
 
 
 
 
 
 
  
  
  
  
   
  
  
  
  
  
 
 
 The purpose of RCOG patient information leaflet is to convey essential information in an accessible 
format. It aims to support the individualised discussion between the clinician and the woman and 
their partner and/or other friends and family and is not intended to be a stand-alone resource.   

All our patient information leaflets are produced in collaboration with service users and clinicians to 
try to ensure that they convey information that is accurate, relevant, clear and succinct. The depth 
of information is agreed after very careful consideration, and with input from service users and 
clinicians, and highlights that additional conversations with clinicians are needed to help personalise 
the risks for an individual.   

In response to your concerns, this patient information leaflet is based on the RCOG Green-top 
Guideline No 45 Birth After Previous Caesarean Birth1 (October 2015). The Green-top Guideline 
states that uterine rupture is a rare but serious complication associated with maternal and perinatal 
morbidity and mortality:  

Women should be informed that the absolute risk of birth-related perinatal death associated with 
VBAC is extremely low and comparable to the risk for nulliparous women in labour.  

Women should be informed of the two-to-three-fold increased risk of uterine rupture and around 1.5-
fold increased risk of caesarean birth in induced and/or augmented labour compared with 
spontaneous VBAC labour.  

Approximately 0.5% risk of uterine scar rupture. If occurs, associated with maternal morbidity and 
fetal morbidity/mortality.  

The guideline stresses the importance of early diagnosis, expeditious laparotomy, and neonatal 
resuscitation to reduce morbidity and mortality related to uterine rupture.  

The guideline also recommends that decisions for induction and augmentation of labour in such 
situations should be made in consultation with senior obstetric input and after informed discussion 
with the woman, in recognition of the increased risks. This being an individualised discussion would 
be outside of the scope of a standard patient information leaflet.  

The patient information leaflet Birth after Previous Caesarean2 , while not using the precise term 
‘fatal’ in relation to uterine rupture nonetheless states the risks and that stillbirth can be a serious 
consequence of VBAC.   

“Serious risk to your baby such as brain injury or stillbirth is higher than for a planned caesarean 
section.”    

“The scar on your uterus may separate and/or tear (rupture). This can occur in 1 in 200 women. This 
risk increases by 2 to 3 times if your labour is induced. If there are warning signs of these 
complications, your baby will be delivered by emergency caesarean section. Serious consequences for 
you and your baby are rare”.  

 
 
 
 
 
 
 
  
  
  
  
  
  
  
  
  
  
 This RCOG leaflet has been reviewed and updated recently and is due for publication in the very near 
future.  

Counselling for VBAC is never a one-off event. Women should be counselled antenatally, with 
information revisited in labour because the risk profile is dynamic, particularly where induction or 
augmentation of labour is being considered. It is the clinical team’s responsibility to ensure that 
women understand not only the numerical risks but also the potential consequences for mother and 
baby.  

It is also important to note that, under the Core Competency Framework developed by the 
Maternity Transformation Programme3 and national partners, all maternity units are required to 
standardise training to enhance safety and consistency in care. Module 3 specifically addresses 
medical emergencies and multi-professional training, with a requirement that 90% of relevant staff 
attend annual in-house MDT training (PROMPT) covering at least four maternity emergencies over a 
three-year period, including uterine rupture, with priorities tailored to local needs. This framework 
reinforces that the unit has a responsibility to ensure that all staff, including those managing labour, 
are trained to recognise and respond promptly to emergencies such as uterine rupture. 
Responsibility therefore extends beyond the individual clinician to the unit’s broader duty to 
maintain competency and preparedness through mandated training.  

Thank you for bringing this to our attention. I hope this is a helpful response to this matter.   

Yours sincerely,  

CEO, Royal College of Obstetricians and Gynaecologists
