The chief of the Care Quality Commission has hit back at claims the body failed to ensure public confidence, insisting it has in fact "made progress".
CQC chief executive David Behan said: "In our strategic review we consulted widely on a clear statement of our purpose and role. We also set out our intentions to improve how we communicate with the public, make better use of information, and work more effectively as an organisation and with others, including those who provide care.
"We have already begun to make some of these changes and will continue this process next year.
"We are focused on protecting and promoting the health, safety and welfare of people who use health and care services."
The comments come after a scathing report by MPs concluded that the regulator of health and social care in England has not earned public confidence.
Failures in the registration process and the handling of a whistle-blowing board member have "further undermined" public assurance in the Care Quality Commission (CQC), the Health Select Committee said.
The body, which inspects hospitals and care homes to ensure standards are being met, was created in 2009. But MPs said the CQC has not yet managed to generate public confidence.
