The couple spoke out as it emerged an independent review into a series of baby deaths is to be expanded after more families came forward.
The Health Service Journal reported more than 60 cases, including baby deaths, brain injuries and deaths of mothers, have been identified.
Concerns were first raised about the hospital’s maternity unit in 2009 following the death of the couple’s daughter Kate Stanton-Davies, just six hours after her birth.
A report found the tragedy was avoidable. Since then, dozens of other parents have come forward fearing their babies’ deaths could have been avoided.
It is alleged that the latest deaths happened in December 2017 when a mother and two babies died in unrelated incidents.
Mr Stanton, 48, said: “Kate’s death was avoidable and so were so many other cases that we’ve heard about. “Many of the families have been extremely brave. They have had to put their head above the parapet and had to battle this trust.”
Ms Davies, 44, of Ludlow, Shropshire, said: “There are 60 cases and that is substantiated even though the hospital trust are trying to deny that. This trust will have to stop being in denial. It is an unsafe trust. Babies and mothers are at risk.
“This has to stop. Not just for me, not just for Richard, not just for our family. It has to stop for all the other families.”
Kayleigh Griffiths, whose daughter Pippa died in 2016 after midwives ignored signs of a serious infection, said the trust is “not open to change”.
She told the Journal: “There are going to be more cases as families are coming forward.”
Last year senior midwife Donna Ockenden was appointed to review 23 cases of alleged poor maternity care at the trust which yesterday said it had written to 12 other families to seek permission for their care to be reviewed.
Chief executive Simon Wright said: “To suggest that there are more cases which have not been revealed when this is simply untrue is irresponsible and scaremongering.”
The trust said it has reviewed 40 cases, 23 of which had no signs of failure of care and five of which the families could not be contacted.
NHS Improvement said it had agreed “to consider additional historical investigations” that have come to light since April 2017.
