Niall Dickson, the General Medical Council's chief executive, said he understood people felt "badly let down" over the fact few have been punished for the failings in basic levels of care which were uncovered at Mid Staffordshire NHS Trust.
Robert Francis QC found a focus on financial performance over adequate staffing was a significant factor in the poor care at the hospital.
Despite what the Francis report described as the "appalling and unnecessary suffering of hundreds of people" and a higher than expected death rate among patients, only a handful of clinicians have faced a professional standards board over their roles.
There will be no further action against four doctors who held management positions at Mid Staffordshire NHS Trust.
The General Medical Council said it was closing the cases after receiving legal advice there was "no realistic prospect of securing a finding against these doctors on the allegations made".
The future of the Trust which runs Stafford Hospital will be outlined as special administrators publish a draft report on service provision.Read the full story ›
Special administrators working at the Mid Staffordshire NHS Foundation Trust will publish their draft report later today.
It is due to recommend how health services should be provided by the Trust in the future.
There is a possibility that the A&E department of the Trust could be told to close. Consultation will begin in August.
Stafford Hospital is to be visited by the new Chief Inspector of Hospitals today to see improvements made since it emerged hundreds of patients died there needlessly due to poor standards of care.
Professor Sir Mike Richards will also talk to staff about their experiences.
Some healthcare assistants are doing jobs which should be done by doctors or nurses without formal training, a review into the profession has found. A review into the profession, initiated after the Stafford Hospital scandal, said the responsibilities of care assistants has become confused:
Healthcare assistants have no compulsory or consistent training, and a profusion of job titles.
Some HCAs are now doing jobs that used to be the preserve of nurses, even doctors.
The review met a group of healthcare assistants from a busy A&E who are inserting IV drips, taking blood and plastering. Yet they are paid at three levels below a newly qualified nurse.
A petition to save Stafford Hospital, which has been signed by more than 50,000 people, is to be presented at the House of Commons later today.
The Trust which runs the hospital is currently in administration.
Earlier this year, health care regulator - Monitor - called for Stafford's Accident and Emergency department to be closed down.
It's the 65th anniversary of the NHS today and it comes as a Midlands MP says its future depends on how the institution reacts to the scandal at Mid Staffs.
Stone MP Bill Cash says Stafford Hospital should keep its acute services to prove the NHS can work properly.
Tory Bill Cash, whose Stone constituency is near the hospital, said the troubled hospital should be given an opportunity to prove itself to establish that the NHS works properly.
A public inquiry into Mid Staffs NHS Foundation Trust found a "disaster" at Stafford Hospital where hundreds of patients may have died needlessly after they were "routinely neglected".
The Francis Report stressed the "appalling and unnecessary suffering of hundreds of people" between 2005 and 2009.
But Mr Cash said Stafford Hospital, which is currently in the hands of administrators, should be allowed to keep its emergency and acute services, which it could face losing.
"The NHS could stand or fall on the results (of the administration).
"We know what's going on in the media, there are a lot of people who are questioning the NHS and with some justification.
"The fact is that if they get this right, the NHS as a whole will benefit enormously."
He added: "I simply ask the Government and ask the minister to make certain that Stafford Hospital is given the treatment and given the opportunity, not only to prove itself, but to prove that the NHS can work properly."
Health Minister Dan Poulter said local MPs, healthcare providers and clinical commissioning groups would be consulted on the decisions.
But he said the Government could not "dictate" what happens as the administrators must make their decisions without political interference.
Dr Poulter said: "I would expect that the Trust special administrator fully engages with key stakeholders in this process, including clinical commissioning groups, local healthcare providers, local authorities and local MPs, which I have been assured is the case."
Health watchdog Monitor has announced the report into the future of the Mid Staffordshire NHS Foundation Trust has been delayed.
The Trust, which runs Stafford Hospital, was put into administration in April 2013 after its services were deemed unsustainable.
Trust Special Administrators have been granted an additional 30 working days to find a way of making health services provided by the trust financially viable after applying for an extension last week.
“The TSAs have been set a complex and challenging task and, while any delay is frustrating for patients and staff, it is important to get it right for local patients.
“Monitor’s Board recognised the scale of the challenges in identifying a solution that meets the needs of the local health economy and asked us to exercise even greater scrutiny at this critical stage.”
The Chairman of the Support Stafford Hospital campaign says it is 'dreadful' that the administrators request for more time to come up with a plan for the hospital has come so late.
Administrators, TSA, were due to report back next week with recommendations for the Mid Staffordshire NHS Foundation Trust after it was found that the trust was not clinically or financially sustainable.
Sue Hawkins, Support Stafford Hospital Chairman said:
"for the public and staff the waiting and anxiety continues. We can only hope that the TSA have realised that there needs to continue to be acute services at Stafford Hospital to serve our expanding community."
The review by administrators followed the conclusion of the Francis Report that hundreds of people suffered unnecessarily at Stafford Hospital between 2005 and 2009, where patients may have died needlessly because of neglect.
