Senior investigation officer, detective superintendent Matthew Croome, announced the move as part of Nottinghamshire Police's Operation Perth investigation.

Nottingham University Hospitals NHS Trust (NUH) is the subject of a maternity review being carried out by Donna Ockenden which is looking into around 2,500 individual cases.

Nick Carver, chair and Anthony May, chief executive of NUH, said: ‘It is absolutely right that we take organisational accountability where we have failed women, families and babies.  

‘We are deeply sorry for the pain and suffering caused. We know that for many families this harm and suffering will be lifelong.    

‘Since joining the board, we have emphasised the importance of openness, transparency and accountability in our leadership and decision-making. We recognise that there is more to do.   

‘Many families have shared their experiences with us, and we remain grateful for their strength and courage after such a harrowing and life affecting tragedy.   

‘We are fully committed to the ongoing police investigation and the Independent Review of Maternity Services, led by Donna Ockenden.   

‘We would like to reassure the public that we are determined to improve our maternity services .  

‘We know how important the police investigation and independent review are for the affected families, the trust and our local communities. We hope that affected families receive the answers that they deserve.'
