A young mother whose baby died at Furness General hospital has described how she felt she was just treated "as a number" by staff at the maternity unit.
Liza Brady's son Alex was stillborn at the hospital in 2008 and since then she and her partner Simon Davey have fought an ongoing battle to raise their concerns.
The couple feel that the Kirkup inquiry's report has vindicated everything they have been fighting for and want action to be taken against those who failed them and the other families affected.
The couple were speaking to ITV News reporter, Mary Nightingale.
The chief executive of Morecambe Bay NHS Trust has admitted there was a cover-up by staff at Furness General Hospital.
Questioned by ITV News, Jackie Daniel said it was "difficult" to come to any other conclusion having read the Kirkup report which looked into failings at the hospital where 11 babies and one mother died.
The chief executive of the NHS Confederation has refused to answer questions about the failings at Morecambe NHS Trust.
Mike Farrar was asked about the independent inquiry after he had hosted a discussion panel at the UK e-Health Week event at Olympia in London.
The chief executive of Morecambe NHS Trust has apologised to "all those who suffered" because of the failings at one its maternity units.
In a press conference, Jackie Daniel admitted there had been serious failings, saying: "The Trust accepts the board's recommendations without reservation. It is a definitive picture of what happened between 2004 and 2013."
The chief executive added that since the Health secretary commissioned the report, the leadership of the Trust had changed and made some improvements which the Kirkup report recognised. However, Daniel realised that there was still much more to, particularly at Furness.
"I would like to add my own apology. During the period covered by this investigation there were some very serious failings," she said. "The Trust then failed to show openness and transparency in acknowledging those failings. So, on behalf of all the staff at the Trust I want to say sorry."

Health Secretary Jeremy Hunt has apologised to "every family that has suffered" as a result of "terrible failures" at Furness General Hospital.
A report published today said a "lethal mix" of problems at the "seriously dysfunctional" maternity unit led to the deaths of 11 babies and one mother.
He described the failings as like a "second Mid Staffs", in reference to the Mid Staffs Hospital scandal, where at least 1,200 patients died because of poor care.
Mr Hunt, who ordered the inquiry, paid tribute to the "courage" of families in their fight for the truth and said they should have been issued an apology earlier.
The Health Secretary said the failings had left "indescribable anguish for the families left behind", adding: "There is no greater pain for a parent than to lose a child and to do so knowing it was because of mistakes that we now know were covered up makes the agony even worse."
Morecambe Bay NHS Foundation Trust have apologised "unreservedly" to the families who suffered as a result of failures in one of its hospital's "seriously dysfunctional" maternity units.
Pearse Butler, Chair of the Trust Board, said: "This Trust made some very serious mistakes in the way it cared for mothers and their babies.
"More than that, the same mistakes were repeated. And after making those mistakes, there was a lack of openness from the Trust in acknowledging to families what had happened.
"For these reasons, on behalf of the Trust, I apologise unreservedly to the families concerned. I'm deeply sorry that so many people have suffered as a result of these mistakes."
The Chairman of the Morecambe Bay Investigation, Dr Bill Kirkup, has said there was a "disturbing catalogue of missed opportunities" at Morecambe Bay NHS Foundation Trust.
He said had proper investigations into serious incidents been conducted as far back as 2004 it would have raised the alarm about the level of maternity and paediatric care being provided.
"There was a disturbing catalogue of missed opportunities, initially and most significantly by the Trust but subsequently involving the North West Strategic Health Authority, the Care Quality Commission, Monitor, the Parliamentary and Health Service Ombudsman and the Department of Health," Dr Kirkup said.
"Over the next three years, there were at least seven opportunities to intervene that were missed. The result was that no effective action was taken until the beginning of 2012."
