A senior NHS official faced calls to resign over his links to a scandal-hit hospital trust where mothers and babies died.
Mike Farrar, who heads the body representing NHS trusts, was in charge of North West Strategic Health Authority (NWSHA) at the time of the failings at Morecambe Bay.
The Parliamentary and Health Service Ombudsman (PHSO) confirmed it was investigating complaints against the NWSHA.
James Titcombe, whose nine-day-old son Joshua died at Furness General Hospital, said Mr Farrar should consider his position as chief executive of the NHS Confederation.
He told the Independent on Sunday:
There was a failure, in my opinion, of the NWSHA in its duty with midwifery supervision. That was a serious failure that is being investigated.
The whole role of the SHA has been highlighted as dysfunctional.
I think (Mr Farrar) should consider his position. He has always said the buck must stop with managers. But he has never taken responsibility for his role at the SHA.
CQC media manager Anna Jefferson has told ITV News that she wanted to "actively waive her anonymity" as soon as she was learned she was to be implicated in the alleged cover-up of the NHS England regulator's failure to investigate a series of deaths at a hospital in Cumbria.
Asked whether it was fair that former Care Quality Commission chief executive Cynthia Bower keeps her pension despite her involvement in the alleged cover-up, the Health Secretary said: "I know the CQC are looking at what sanctions they have against people who may have been involved".
Jeremy Hunt added that people should face "serious consequences" if it is proved they were involved in any cover-up:
He also said that he would back CQC "to the hilt" if they decided to take any action against those allegedly involved.
Health Secretary Jeremy Hunt said he had "confidence" in the two new people in charge of the Care Quality Commission to "turnaround" the NHS England regulator after it allegedly covered-up its failure to investigate a series of baby deaths.
Mr Hunt added that he was "not happy" with inspections by the CQC, during an interview with BBC Breakfast.
The Health Secretary Jeremy Hunt has told Daybreak he wants a barring system to stop NHS staff who have failed in their jobs from being able to work elsewhere in the health service.
He said: "We are fed up with people who do something terrible in one part of the NHS popping up somewhere else."
Talking about the position of chief executive of the NHS, Sir David Nicholson, Mr Hunt said: "I do not happen to think he was personally responsible for what happened at Mid Staffordshire but what I do want is total accountability."
The current chair and chief executive of the CQC are set to give evidence to the Health Select Committee after it emerged that the health watchdog covered-up its failure to investigate a series of baby deaths.
Health Select Committee chair Stephen Dorrell told the BBC Radio 4 World Tonight programme he will call the current chair and chief executive of the CQC to give evidence after it emerged that the health watchdog covered-up its failure to investigate a series of baby deaths.
At the heart of the Morecambe Bay NHS Trust scandal is anguish of grieving families - the families who were at first denied the chance of learning about the failings behind the loss of their loved ones.
